Abstract

A method of making a plurality of individual prints on a single sheet of photographic print paper is disclosed herein along with a particular easel arrangement for carrying out this method. The easel arrangement includes a fixed planar surface of sufficient size to support the photographic print paper for movement between a number of different positions, each corresponding to the placement of a particular print on the overall sheet. In order to make the individual prints, this sheet is manually moved to its various positions with the aid of stop members which engage the leading edge of the sheet but which are readily movable out of engagement therewith. In this way, the sheet of photographic print paper can be easily and accurately moved from position to position.
