ABSTRACT:
A portable display apparatus is herein disclosed. The portable display apparatus is composed of a plurality of rectangular skeletal frames. Each rectangular skeletal frame of the plurality includes a horizontal hinge adapted to enable vertical members of the frame to fold vertically. Each of the vertical members has a connector portion and a pair of track portions. Each of the vertical rectangular skeletal frames is adapted to be connected to a dovetail slide connector to other rectangular skeletal frames. The dual track portions are adapted to receive a pair of display panels. The dual track portions are positioned so that connector portions of the dovetail connectors do not interfere with the track portions or display panels.
