Notes on this view:

This Polacolor peel-apart print is 3 1/4 x 4 1/4 inches; a standard size for pack film. It is likely an example of Type 108 film, a popular amateur color film released in 1963.

In 1944, inventor and Polaroid co-founder Edwin Land began experimenting with methods of producing instant photographic prints. Though the company’s first commercial products were black and white, color images were sought after from the start. Polacolor, using an entirely new system of color processing, was released in 1963 as Polaroid’s first color film. The process was devised largely by Howard Rogers, Director of Research, and incorporated newly designed dyes that “hitched” each dye to a developer molecule. These dye developers allowed for controlled formation of color images with almost no effort from the photographer. Once an exposure was made, the film pack was pulled through the camera’s rollers to rupture the reagent pod and spread the processing chemistry. After 60 to 90 seconds the pack was peeled apart revealing a color negative and color positive print. The chemical pod and negative were discarded.
