Abstract

A double sided table top display apparatus having a first double sided upright sub-assembly, a second double sided upright sub-assembly, and upper and lower horizontal cross-members, which extend between the first and second double sided upright sub-assemblies, to substantially span the desired length of the table top. A one or more horizontal cross member extension(s) may be selectively used to extend the length of the display apparatus for longer displays. A flexible sheet material with indicia thereon is releasably secured to the modular table top display apparatus at assembly, and may be rolled up for transport or storage. A rotatable clamp extends beneath the table top to secure each of the first and second upright sub-assemblies directly to the table top. Optional lighting may be supported by the rigid frame. The modular table top display apparatus my be disassembled and compactly stored in a carrying case or bag, for ease of transport and storage.
