At the Anniston Museum of Natural History we have constructed modular wall units that supplement our existing temporary exhibit space. We have approximately 200 running feet of wall space which is almost doubled by the units. Each unit is 8' h x 4' w x 2' d. Each unit can also be broken down into smaller units to act as barricades, bases, stands, etc. Units can stand upright against a wall or can be free standing on the floor. We have on occasion placed them flat on the ground to display large 2-D objects such as rugs and other textiles. I'm not certain of the price per unit, however they are constructed of 1/2" plywood with a 2" x 4" frame. and they work just fine for our busy schedule of temporary exhibits. Please feel free to contact me via the internet if have any other questions. Paul M. Legris Exhibit Designer Anniston Museum of Natural History - [log in to unmask]
