Abstract
An overlay tray for holding a plurality of photographic slides in side-by-side relationship is integrally formed from transparent plastic and defines a series of parallel, longitudinal channels. Each channel has a longitudinal groove adjacent one channel wall so that pressure applied to the edge of the slide above the groove pivots the opposite edge of the slide outward from the channel. The walls of the overlay tray are constructed so that the trays may be stacked one upon the other in interfitting relationship with the bottom of one tray retaining the slides in fixed position within the tray below. A flange extends from one end of the overlay tray so that an identifying label placed thereon can be read through a stack of such trays.
