The Ralston, G. mss., 1916-1949, consists primarily of lantern slides collected by Glenn Ralston. Most of these slides were produced to be used in movie theatres to announce coming attractions and to advertise various products and services. A few informational slides are included, such as "Silence," "Children of Europe Need Your Help," "Let Us Stand By President Wilson," and several offer song lyrics. In addition, there are 63 lantern slides pertaining to homeopathy. A sheet music cover and its copper printing plate for an unknown piece from the film The Emperor Waltz starring Bing Crosby and Joan Fontaine complete the collection.
