Large collection of 4 x 5'' glass lantern slides, each with colorful advertisements for movies. These were shown in early theatres similar to the way that movie previews are today to promote upcoming flics. Stars such as Buster Keaton, Glorida Swanson, Tom Mix, Douglas Fairbanks, Lionel Barrymore, Pola Negri, Ben Turpin, Mary Miles Minter and many more are featured. A full list is available. Condition: A few stray cracks and scratches, but overall excellent.
