These viewers were often shaped like small tubes, boxes, binoculars, cameras, or simple plastic cases. The one shown in the image has a pink plastic body, a light-colored viewing end, and a small metal chain, making it easy to carry on keys, bags, or purses.
When Did It Become Popular?
The idea of tiny image viewers goes back much further, but the plastic keychain photo viewer became especially popular in the United States during the mid-20th century, particularly from the 1960s through the 1980s.
During that time, these items were often sold or given away as souvenirs, promotional gifts, novelty toys, and keepsakes. Tourist attractions, amusement parks, fairs, churches, schools, and businesses sometimes used them to show a tiny photo of a place, logo, religious image, family picture, cartoon, or scenic view.
For many people, receiving one felt special because it was like carrying a secret little picture in your pocket.
What Was It Used For?
The main purpose of a keychain photo viewer was simple: to let someone view a tiny picture through a small lens or opening.
