The frame is for the exhibition of photographs or items in a collection having a main supporting piece with a peripheral portion protruding at right angles to it at front and reat. The rear face of the piece has central protrusions at the centre and in a straight line, integral with which are feet at right angles to them at points adjacent to the peripheral portion. In front of the front face of the supporting piece is a window, with a beaded edge engaging with the peripheral portion and holding it in place, while allowing removal.
