Abstract
Abstract A frame for receiving removably at least one two-dimensional visual object has edge supports for receiving therein the edges of the object, and a back support connected with relation to the edge supports, for the supporting of the object when placed in the frame. The edge supports are spaced apart from each other for a distance slightly smaller than the corresponding dimension of the flat object thus, the object when placed into the frame will assume a concave position lying against the back support.
