Abstract: A desk-top picture gallery adapted selectively to display any picture in a deck of photo prints all of the same size. The gallery is constituted by a frame-pocket assembly supported on a detachable easel. The box-like pocket which accommodates the deck of prints is secured to the rear of the frame behind its opening, the pocket having a front window which exposes to view whichever print then occupies the first position in the deck. The easel is provided with a step on which the pocket rests, the step having a ridge thereon which is socketed either within a complementary slot in the closed end of the pocket, in which case the assembly is then vertically oriented, or within a complementary slot in either of the two sides of the pocket, in which case the assembly is then horizontally oriented. To interchange the picture on display with another selected from the deck, the selected print is transferred to occupy the first position in the deck.
