     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring now to FIGS. 1-4, the apparatus of the invention is identified by reference number 21. It comprises top and bottom members 23 and 25 formed of a light weight and relatively rigid material such as wood. The members 23 and 25 could be formed of other materials such as aluminium. Member 23 is round and has a lower end 23L, an upper end 23U and an outer cylindrical side 23S. Member 25 is round and has a lower end 25L, an upper end 25U and an outer cylindrical side 25S. A bladder 27 having an inner cavity 27C formed of a flexible and stretchable material is provided. It can be formed of different materials, however, in one embodiment it is formed of 20 mil. vinyl. The bladder 27 has a cylindrical side wall 27S and top and bottom walls 27T and 27B defining the cavity 27C. The bladder is folded at 27TF and 27BF forming two cylindrical end member reception zones 23R and 25R for receiving the end members 23 and 25 respectively. The end members 23 and 25 each has a diameter and thickness greater than that shown such that they are snugly received in zones 23R and 25R respectively with the lower surface 23L and cylindrical side wall 23S of member 23 engaging the top wall 27T and the inside cylindrical wall of folded portion 27TF and the upper surface 25U and cylindrical side wall 25S of member 23 engaging the lower wall 27B and the inside cylindrical wall of folded portion 27BF. The inside surfaces of folded portions 27TF and 27BF are fixedly secured to the sides 23S and 25S of members 23 and 25 with a suitable glue or adhesive. A plurality of elongated non-stretchable, flexible tension bands or strips 31 are provided. Each of the bands 31 has an upper end 31U and a lower end 31L which are folded around to engage the upper and lower surfaces 23U and 25L respectively of end members 23 and 25 and are secured thereto by glue or by nails or screws (not shown). In the embodiment shown, three members 31 are provided secured to members 23 and 25 such that adjacent members 31 are spaced 120 degrees apart. The number of members 31 used depends on the size of the device. For example there could be six of the members 31 with adjacent members 31 spaced 60 degrees apart. The members 31 are located on the outside of the bladder 27S. Two flexible hook side strips 41 and 43 are secured around the top and bottom ends of the assembly such that strip 41 is secured around the top ends of strips 31 around the outer side of the folded position 27TF and hence around the side 23S of member 23 and strip 43 is secured around the bottom ends of strips 31, around the outer side of folded portion 27BF and hence around the side 25S of member 25. The strips 41 and 43 have hook fasteners 41H and 43H respectively formed on their outer sides. 
     A flexible sleeve 51 is provided having &#34;loop&#34; fasteners 51L formed on its outer side. The top and bottom ends 51T and 51B are folded and secured inward such that their loop fasteners 51L face inward and engage the hook fasteners 41L and 43L of members 41 and 43 to secure the sleeve 51 to the strips 41 and 43 and around the assembly including strips 41 and 43, bands 31, bladder sleeve 27S and end member 23 and 25. The bladder 27 has a one way valve 27V for inflating and deflating the bladder. The valve 27V may be of the type used in air mattresses and has an interior one-way flapper valve. The valve 27V is aligned with an aperture 25A formed through member 25 to receive a hose 81 attached to an electric pump 83 operated by an AC power supply 84. The member 25 also has three apertures 25AI for receiving screws 61 which are attached to legs 63. 
     An electrical lead 65 is provided which extends from a male socket 65M inside of the sleeve 51 and strips 43 and 41, through and aperture 21A1 and upward through an aperture 23A2 formed through member 23 to an female socket 65F. A threaded Tee member 67 is provided which extends through an aperture 21A3 of member 23. The member 67 has threads formed on its stem for allowing another threaded member to be attached thereto for allowing signs, etc. to be attached to the top of the apparatus. A top circular sheet 51TS with loop fasteners 51L is attached to the top of the apparatus 21. It has an aperture 51TA for allowing entrance to the female plug 65F. A cover having hoop fasteners is employed for covering the plug 67F when not in use. If desired the lead 65 and socket 65F at the top may be loose without the lead extending through apertures 21A1 and 21A2. 
     In a storage condition, the bladder 27 is deflated and the bladder wall 27S, strips 31 and sleeve 51 are folded to allow the end members 23 and 27 to be moved close to each other as shown in FIG. 1. This facilitates storage and transport of the member 21. When it is desired to set up the display apparatus 21, the hose 81 is connected to the valve 27 and the pump 83 operated to inject air under pressure into the cavity 27C of the bladder 27. As the bladder inflates, the end wall 23 moves upward away from end wall 25 and the display sleeve 51 expands upward to an extended position as shown in FIGS. 2 and 3. As the end wall 23 moves upward, the tension strips 31 are extended upward. Since the strips 31 are substantially non-stretchable, they limit the upward expansion of the bladder 27 and upward movement of the member 23 and hence prevent damage to the sleeve 51 which may tear if it is stretched too far. The strips 31 also keeps the top and bottom members 23 and 25 in the desired relationship to each other when the bladder is inflated and expanded. Attachment of the top and bottom ends of the sleeve 51 to the members 23 and 25 limit outward radial expansion of the sleeve 51 upon inflation of the bladder. After the bladder 27 has been inflated a desired amount, the hose 81 is removed from the one way valve 27V whereby the apparatus 21 may be used for display purposes. In this respect, products 71 having hooks fasteners 73 attached thereto are easily secured to the sleeve 51 as shown in FIG. 2. 
     The purpose of the lead 65 is to operate lights which may be carried by a sign attached to Tee 67. 
     When it is desired to disassemble the apparatus 21, the products 71 are removed from the wall 51, and the flapper valve of the valve 27V pushed inward to allow air in the cavity 27C to be released to deflate the bladder 27 to allow the end members 23 and 27 to be moved toward each other and the bladder wall 27S, strips 31 and sleeve 51 to be folded to place the apparatus in a compact folded condition as shown in FIG. 1. 
     In one embodiment, the members 23 and 25 each may have an outside diameter of 28 inches. The height of the apparatus 21 with the bladder inflated may be 58 inches. It is to be understood that the apparatus 21 may have other dimensions. The strips 31 may have a width of 1/2 of an inch. They may be formed of polypropylene having a tensile strength of about 400 pounds per half inch. Under the load imposed herein they will not stretch. The strips 31 also may be formed of other materials such as polyester stranded banding material having a tensile strength of about 2000 pounds per half inch. 
     The bottom member 25 can be attached to a stand rotated by an electric motor if desired. 
     The shape of the apparatus of FIGS. 5 and 6 is the same as that of FIGS. 1-4. 
     Referring to FIGS. 7-14, the apparatus shown therein employ the basic components of FIGS. 1-4, however, the top and bottom members 23 and 25 of the apparatus are modified to provide the shapes shown. In these Figures, the bladders are in inflated conditions. In FIGS. 7 and 8, the side wall of the apparatus is cylindrical, however, the top wall forms an acute angle relative to the bottom wall. In FIGS. 9 and 10 the apparatus is in the form of a truncated cone with the top wall having a diameter smaller than that of the bottom wall. In FIGS. 13 and 14, the apparatus is in the form of a truncated cone with the top wall having a diameter larger than that of the bottom wall. In FIGS. 11 and 12, the apparatus has two flat sides with rounded ends when viewed from the top and bottom. The bladder has interior partitions 27P with interior passages (not shown) such that it can be inflated from a single valve.
