This is a small 12 page Keystone film catalogue that would have come with a projector. It is 7.75″ by 5.5″. It lists about 200 films including Charlie Chaplin, westerns, Disney cartoons, Shirley Temple, travelogues and numerous cartoons. There are some film supplies listed and instructions on the Keystone film exchange plan. I would estimate this catalogue to be from the 1930’s.
From my private collection.
