ABSTRACT:
A picture viewer has a housing for a pile of pictures, a window for viewing the pictures, and a slider which is used to transport a picture from one side of the pile and guided to the other side of the pile again as the slider is operated. A retaining device selectively operates to prevent the remainder of the pile from being transported out of the housing.
