Abstract: A display frame system comprises hexagonal or octagonal posts and strut assemblies which connect the posts to each other. The posts may be positioned in any of a variety of arrangements depending upon the available space and type of display to be erected. Once the posts have been connected to each other, panels carrying advertising material may be slipped into slots in the posts. The posts are arranged so that each post has a slot which faces a corresponding slot on an adjacent post. Opposite edges of the advertising material are received in the slots in each posts. The display frame system also includes a variety of illumination panels. These are panels which are also mounted between opposing slots in the posts and which carry light fixtures which can either illuminate advertising material from behind or from above, depending upon the configuration of the illumination panel and the arrangement of the posts.
