A photograph printing apparatus arranged to print a main picture and an illustration picture in a single frame on printing paper. The apparatus has a main picture negative film mount for carrying a negative film having the main picture and an illustration negative film mount for carrying a negative film having the illustration picture. The former film mount and the latter film mount are arranged to interlockingly move in the same direction to alternatively travel toward and away from the optical axis of exposure light. This arrangement enables rapid printing of photographs.
