     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring now to the drawings, the basic structure A of a sign configured in accordance with the present invention. Sign structure A comprises a frame 12 of generally rectangular shape, having somewhat greater height than width. Frame 12 is constituted by joined metal tubular upper and lower portions 13, 14, together carrying a metal display sheet 15 with said frame surrounding said sheet in effect. Frame portions 13, 14 are each formed, as by bending, into generally U-shaped configurations, being joined together at joints 16, 16&#39; to define straight sides 17, 17&#39; of the frame, and straight top and bottom portions 18, 19 of the frame, but with rounded corners, as at 20, 20&#39;. 
     Joints 16, 16&#39; are constituted by a butted relationship of the upper and lower frame portions 13, 14 as shown in FIG. 3 wherein it is seen that the respective ends of the upper and lower portions are butted together at the midpoint of the sign, a reduced diameter length of tubing, as at 21, is telescoped within the butted ends, which are then welded together, as at 22. Below said joints 16, 16&#39;, respective apertures 23, 23&#39; are provided which extend transversely through the tubing of the lower frame portion 14. 
     Sheet 15, which may be of aluminum alloy, is carried within the inner periphery of frame 12. For this purpose, sheet 15 is provided with rounded flanges or lips 24, 24&#39; along its side edges and 25, 26 along its respective upper and lower edges. Said lips are secured to the tubular frame 12 as by screws 27. Alternatively, sheet 15 may be riveted or welded in place, etc. 
     Sheet 15 can carry upon its face pairs of parallel, oppositely disposed tabs 29, 30 defined by lengths of material extending horizontally upon the face 28 of the sign and upset from the plane of the sheet. Each tab of a pair opens toward the other tab, as shown in FIG. 2, so that each tab pair 29, 30 may receive and secure upon face 28 panels (not shown) carrying various numerals, letters, characters, or other indicia. For example, the panels may display the price of motor fuel. Or they may display various legends such as will indicate goods or services offered by a place of business. There are three such pairs of tabs 29, 30 to display three lines of information. Various other panel mounting arrangements may be employed such as channel rails, screw studs, etc. 
     For purposes of mounting frame 12 in a preferred mode of sign construction, the upper and lower portions 18, 19 can each be provided with five apertures 31 which extend transversely through portions 18, 19 normal to the plane of sheet 15, these being in addition to the apertures 23, 23&#39; below the joints 16, 16&#39;. 
     Referring to FIG. 5, the basic sign A is configured as a sign embodiment B which shown mounted to a pole or tubular standard 32 such as may already be present. For this purpose, sign A has secured along its lower and upper portions 18, 19 respective brackets 33, 34 of U-shaped cross-section, as seen in FIG. 6. Said brackets preferably have an inside width corresponding to the outside diameter of frame portions 18, 19 to fit tightly thereon, being secured by bolts 35 extending through apertures 31. 
     Each said channel 33, 34 extends beyond the right hand edge of the sign and carries at its respective outer end 33&#39;-34&#39; (as shown in FIG. 7) curved fittings 36, 37 confirming to the circular cross-section of standard 32. Similar curved fittings 38, 39 are provided which are bolted together by bolts 40 to clampingly surround standard 32. Thus, the channels 33, 34 are clamped to standard 32 at the top and bottom of the sign. 
     FIG. 8 demonstrates another embodiment C of the sign made possible by alternative securement of frame 12. Such entails the bolting securement by bolts 41, 41&#39; below joints 16, 16&#39; of short channels, 42, 42&#39; which said bolts 41, 41&#39; are placed through apertures 23, 23&#39; for this purpose. Said channels are of U-shaped cross-section, opening toward sheet 15. Each said channel carries an end threaded pin or stud 43, 43&#39; which projects perpendicularly and laterally outwardly from the channel bracket for serving as a pivot. For this purpose, each pivot pin 43, 43&#39; is received within a respective transverse slot 45, 45&#39; (FIG. 9), located in the upper end of a respective support 46, 46&#39; located at the opposite sides of the respective frame portion 17, 17&#39; and so constituted by upright portions of a member 47 of U-shaped configuration which conforms to the shape of frame lower part 14. Said supports 46, 46&#39; are of tubular steel, as shown in FIG. 10. Extending the width thereof are bushings, as at 44, in which the respective pivot pin may freely rotate. Preferably such bushings 44 are fitted within slots and retained therein by cross-pins or bolts 49, 49&#39; extending through the upper end of supports 46, 46&#39;. 
     Said member 47 is supported by pairs of legs 48, 48&#39; which extend outwardly from the sign in opposite directions to provide a broad, stable base for the sign. Member 47 and legs 48, 48&#39; may, for example, be of steel tubing of square cross-section. 
     For maintaining sign panel 15 in upright disposition, a counterweight 50 is bolted to the lower edge tubular member 19, as shown in FIG. 11. Counterweight 50 is constituted by a channel member 51 considerably greater depth than the diameter of frame member 14 to provide a space within the channel member for a heavy bar 52, such as of steel. 
     Accordingly, frame 12 of embodiment C is free to swing on pivot pins 43, 43&#39; in response to being struck, as by a person or vehicle, without causing substantial damage to the striking instrumentality or to the sign frame 12 or panel 15. Further, since the cross-sectional area of panel 15 above the pivot axis is considerably greater than that below the pivot axis, wind striking the panel 15 will merely cause frame 12 to pivot harmlessly, without causing the entire sign C with its frame 47 to be blown over. 
     Referring now to FIGS. 12-14, indicated at D is an embodiment of the sign wherein the basic sign A is shown mounted to a pole or other tubular standard 32 of pre-existing type. Although pole 32 is of circular cross-section, it may be rectangular, ellipsoidal, or of other common cross-section. Pole 32 may be several inches in diameter. In embodiment D, sign panel 15 is affixed to pole 32 in such a way that the sign is centered with respect to the pole, and lies in a plane parallel to and adjacent the longitudinal, or vertical, axis of the pole. 
     For securement to the pole, there is affixed to the frame 12 of the sign at its top and bottom respective bracket clamps 54, 55. 
     Each said clamp 54, 55 is of the configuration shown for clamp 54 in FIG. 14. There, the upper frame member 13 has provided through two of its apertures 31 a respective threaded rod 57, 57&#39;. Said threaded rods extend through the opposite ends of each of a pair clamp brackets 58a, 58b each of which is of U-shaped cross-section, as seen more clearly in FIG. 13. As will be apparent, apertures are provided at the opposite ends of each of these brackets members for receiving the threaded studs 57, 57&#39; and with the channels or recesses of said channel members opening toward one another for clampingly receiving tube 32 therebetween. Nuts, as at 60, 60&#39; are provided at opposite sides of the bracket members 58a, 58b for causing compression of these bracket members toward one another for tight engagement of the vertical posts 32. For enhancing the gripping engagement of the latter, each of bracket members 58a, 58b is provided also with a V-shaped recess in its flanges as at 61a, 61b thereby to provide a tooth-like sharp edged series of surfaces for bittingly engaging the periphery of the post or tube 32 to more securely clamp the brackets in position. 
     In a preferred manner of installation, the threaded members can be dispositioned within the brackets to a desired outward extension of the threaded studs for allowing sign frame 12 to be placed at a desired spacing outwardly from the post 32. The upper and lower frame members respectively, of the sign frame 12 are clampingly engaged to these threaded studs by nuts tightened in opposition, as indicated at 63, 63&#39;. 
     Manifestly, the same frame 12 is utilized to construct the basic sign embodiment A, the pole or standard-mounted embodiment B, the pivoted free-standing sign embodiment C, as well as the pole-centered embodiment D, all without altering the fundamental frame structure, yet conducing to simple, speedy alteration of the mounting configuration by even relatively unskilled persons. Further, manufacture of frame 12 contemplates merely the forming of two frame elements 13, 14, which may be simply of economical steel tubing, into required U-shaped configurations and with simple joinder thereof at joints 16, 16&#39; so that the frame 12 is self-supporting and ready for having panel 15 secured to it. Thereafter, the desired attachment mode, as for either embodiment B, C, or D, is easily realized by the mounting of the desired complementarily-shaped brackets 33, 34 or 42, 42&#39;, or as desired, to the universal frame 12. 
     Although the foregoing includes a description of the best mode contemplated for carrying out the invention, various modifications are contemplated. 
     As various modifications could be made in the constructions herein described and illustrated without departing from the scope of the invention, it is intended that all matter contained in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative rather than limiting.
