  • Sliding panel photographic card
    Patent number: 7007365
    Abstract: A sliding panel display device for displaying two different images, such as photographs, comprises front and rear panels, each bearing a different image or photograph, and each divided into a plurality of parallel strips. The strips of the front panel are arranged as slidable interleaves between the strips of the rear panel, whereby the strips of the front panel are movable between a first position, in which the strips of the rear panel are completely covered by the strips of the front panel, and a second position, in which the strips of the front panel are completely hidden behind the strips of the rear panel whereby in the first position, only the image on the front panel is visible, while in the second position, only the image on the rear panel is visible. These panels are held together in the interleaved relationship in a holder that forms a frame. The rear panel is fixed in the holder, while the front panel is held in the holder so as to be slidable between the first and second positions.
