Modular wall system for exhibition booths

A modular wall system for use in trade shows includes a wall or header panel formed of frame parts, and a connecting bracket for detachably connecting the end of the panel to an upstanding column. Perpendicular sections of a corner connector are received in the hollow end of different ones of the frame parts to connect the frame parts. A fabric cover defines a recess with an open end adapted to receive the frame parts. A closure device is provided for at least partially closing the open end of the fabric cover. A vertical support member extends from the frame parts to a surface to transmit the weight of an accessory to the surface. The accessory may be an adjustable garment rack, a coupling grid, a shelving unit, or a peg-board unit and a hook. The system includes a crate adapted to receive a plurality of members for transport.
