Abstract
A display frame construction employs spaced end plates having at least two contiguous curved edges to receive at least two webs or sheets carrying graphic displays. Interposed slotted spacer members which interfit with and maintain the plates in spaced generally parallel relation may be employed to receive the contiguous edges of the displays. Edge portions of the plates are also slotted along the curved edges whereby two opposed edges of a rectangular picture or other display web may be received in plate slots which follow the edge contours of the plates and the other pair of opposed edges of the display may be received in the slots of the spacer means. The plates and spacers may interlock or resilient means between the plates may be employed to maintain the frame components in a state of assembly.
