Notes on this view:

This Polacolor snapshot exhibits no prominent dye fading and has vivid color saturation. The 3 1/4 x 3 3/8 inch format indicates this print as Polaroid Polacolor Type 88.

Polacolor Type 88 was a square format Polaroid "peel-apart" film introduced in 1971. Polacolor is the trade name for the complicated dye diffusion transfer process invented by Edwin H. Land of the Polaroid Corporation. The film "pack" included a light sensitive negative film, positive receiving sheet, and a pod containing processing chemicals. The film was exposed in camera and was pulled out of the camera through metal rollers causing the pod to break open and spread the processing chemicals evenly across the film. After roughly 60 seconds the pack was peeled apart revealing a color negative and color positive print. The chemical pod and negative were discarded.
