Abstract

A photographic easel for making borderless prints has a laterally adjustable bar positionable by bolts movable in a pair of parallel slots and is otherwise formed of a generally rectangular metal sheet having bent-up edges. A back and side edge are bent at an angle of about 10.degree. from the vertical toward a central region of the sheet to form abutments for two adjacent edges of a sheet of print paper, and a front edge is bent up at an acute angle to the horizontal plane of the metal sheet to form a finger grip for manually positioning the easel. The bar is generally channel-shaped with a vertical edge and an inclined edge and is preferably reversible, and five support pads are secured to the underside of the sheet to uphold the corners and a central region above a support surface to provide clearance for the bar-retaining bolts.
