发明名称 Display frame
摘要 A pair of frame elements, between which a photograph is held, are preferably formed of a clear, transparent plastic material, each frame element having a flat horizontal bottom portion and an upwardly directed, sheet-like portion. To the underside of the box of the front frame element are fixed a pair of spaced guide strips which extend beyond the upwardly directed portion and rearwardly, while a second pair of similarly formed guide strips extends forwardly from the underside of the base of the rear frame element. The guide strips engage each other in sliding contact when the front and rear frame elements are pushed together to clamp the photograph. In addition it is desirable to provide on the underside of each base a downward projection, about which projections an elastic band is stretched to hold the photograph releasably clamped between the front and rear frame elements.
