     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     In the exemplary embodiment of the invention as disclosed in FIGS. 1-4 of the drawing, a display device generally designated 10 is shown to comprise a pleated sheet generally designated 11 retained in a corrugated display configuration by a carrier generally designated 12. 
     As best seen in FIG. 1, carrier 12 defines an upper end portion defining a first pocket 13, and an opposite second lower end portion defining an opposite pocket 14. The upper end of the pleated sheet 11 is received in pocket 12 and the lower end is received in pocket 14 so as to expose a midportion generally designated 15 of the pleated sheet for presenting two segmented alternative displays depending on the position of the viewer. 
     More specifically, as seen in FIG. 4, the pleated sheet 11 defines first alternating corrugation surfaces 16 and second alternating corrugation surfaces 17 intermediate surfaces 16. Thus, when viewed from the direction of the arrows A. the display on surfaces 16 is seen, whereas when viewed from the direction of arrows B, the display on surfaces 17 is seen by the viewer. 
     The invention comprehends a novel arrangement of the carrier for retaining the pleated display sheet snugly in the carrier without the need for fastening means, such as adhesive, staples, etc. More specifically, as shown in FIGS. 3 and 4, the carrier defines a midportion 18 provided with stop means 19 at its opposite edges defined by upstanding walls. As shown in FIG. 4, the edge walls 19 are configured to be received within the side edge corrugations of the pleated sheet 11 so as to limit lateral expansion of the pleated sheet to the configuration illustrated in FIG. 4 wherein the height of the pleats is substantially equal to the depth of the pockets 13 and 14, as furthere shown in FIG. 2. Resultingly, the pleated sheet is snugly retained at each of its opposite ends in the pockets by the resilient tendency of the sheet itself to expand toward a planar configuration from the pleated configuration. 
     As shown in FIG. 9, carrier 12 may be formed from a single sheet of suitable material, such as paperboard, defining a blank 20 having suitable score lines 21 for facilitating folding of the sheet into the carrier configuration. As illustrated in FIG. 3, the pocket 12 is firstly folded and secured, permitting the upper end 22 of the pleated sheet to be inserted into the pocket as a first step in the assembly of the display device. 
     The folded sheet is then brought into juxtaposition to the carrier midportion 18 and the lower pocket 14 formed about the lower end 23 of the sheet, as seen in FIG. 2. The pocket portions of blank 20 are provided with suitable locking tab sections 24 for securing the blank portions in the pocket-forming configurations. 
     The final step in the assembly of the display device comprises a step of urging the stop walls 19 under the side portions of the pleated sheet to the configuration illustrated in FIG. 4, wherein the stop walls 19 limit further expansion of the midportion 15 of the pleated sheet and cooperate with the pockets 13 and 14 in effectively retaining the pleated sheet in display disposition in the device 10. 
     As best seen in FIG. 9, the blank 20 may be provided with suitable score lines to define an easel support 25 adapted to be pressed out of the carrier portion 18 and permit the display device to be self-standing on a subjacent support surface in the manner of a conventional easel-type photograph frame. 
     Thus, the display device 10 comprises an extremely simple and economical construction, being formed of two pieces of paperboard or the like suitably cut, scored and folded to define the improved structure wherein the display sheet is snugly retained in the carrier without the need for fastening means. Further, the assembly is readily and quickly effected. As indicated above, the easel support 25 permits the device to be set on a subjacent supporting surface. Alternatively, as seen in FIGS. 2 and 9, the rear wall of the carrier may be provided with a pushout wall hanging portion 26, permitting the carrier to be hung on a nail or hook so as to be wall-mounted when desired. 
     Referring to the embodiment of FIGS. 5-8 and 10, a modified form of display device generally designated 110 is shown to comprise a pleated sheet 111 received in a carrier 112. Carrier 112 defines an upper pocket 113 and a lower pocket 114 for receiving the upper and lower ends of the pleated sheet 111 in a manner generally similar to that of display device 10. 
     However, carrier 112 further defines side edge pockets 127 and 128 extending between end pockets 113 and 114. Thus, carrier 112 effectively defines a complete frame for the pleated sheet 111. Thus, in lieu of the stop walls 19 of device 10, the sidewalls 127 and 128 embrace the edge pleats of the display sheet 111 so as to effectively limit the lateral expansion of the pleated sheet upon reception in the frame carrier. 
     The configuration of the carrier is made to cause the pleating of sheet 111 to have a height substantially equal to the depth of the pockets, as shown in FIG. 8. 
     As seen in FIGS. 5 and 6, the front wall 129 of the carrier is provided with an opening 130 exposing the midportion 115 of the pleated sheet and, as shown in FIG. 6, the rear wall 131 is provided with an opening 132 exposing the rear surface of the midportion 115. Thus, the display device 110 provides four different displays depending on the positioning of the viewer. More specifically, as seen in FIG. 8, the pleated sheet defines first alternating surfaces 116 and second alternating surfaces 117 intermediate surfaces 116 for providing two different displays viewable from the front of the device. 
     As further shown in FIG. 8, the rear surface of the display device defines alternating third surfaces 133 viewable in the direction of the arrows C and fourth surfaces 134 viewable in the direction of arrows D intermediate surfaces 133 so as to provide third and fourth displays selectively viewable depending on the position of the viewer looking at the rear of the display device through the window 132. 
     Display device 110 is advantageously adapted to be supported from an overhead support as by a hanger element 135 so that the display device is free to move relative to the viewer and thereby present the different displays with the viewer remaining in a single position. Thus, the display device 110 is advantageously adapted for use in presenting advertising displays which are uniquely attention-catching, while yet the display device is extremely simple and economical of construction. 
     Carrier 112 is adapted to be formed from a single sheet of material from a blank 136, as shown in FIG. 10, provided with score lines and slits so as to permit facilitated forming of the carrier from the blank by the user. As further illustrated in FIG. 10, the blank includes tabs 124 cooperating with suitable slits 137 for securing the blank in the carrier configuration without the need for additional securing elements. 
     Thus, display device 110 is similar to display device 10 in being formed of two novel elements which may be readily formed into the display device configuration by the user and readily assembled to form the desired configuration. 
     It should be noted that in the display device 10, while the carrier defines a rear wall 18 which would normally prevent observation of the rear surface of the pleated sheet, the sheet may be provided with displays on both the rear and front surfaces so that the display sheet may be selectively installed with either of the two faces thereof exposed forwardly for viewing of the two displays carried on the alternating corrugated surfaces thereof. 
     The foregoing disclosure of specific embodiments is illustrative of the broad inventive concepts comprehended by the invention.
