Abstract
A picture display comprising elemental prints having enlarged divisional images with separation arranged in a matrix on a print holder so as to form a single picture, and a printing method and apparatus for making the picture strips as the elemental prints from a single frame of an original film. The printing apparatus has a printing stage movable in two directions perpendicularly intersecting each other so as sequentially to place divisions into which the image frame of the original film is notionally divided in a matrix in printing position for exposing a photograhpic paper to enlarged divisional images of the divisions in order by column or row, thereby making a picture strip with a row or a column of the enlarged divisional images formed thereon.
