One of 14 "Motion Picture Etiquette: Lantern Slides" from 1912, courtesy of the Library of Congress and Click Americana.
The Library of Congress, who own the original lantern slide prints, describe them as text “superimposed on humorous photograph, and the whole shown in a fancy carved frame.” These images were created by Scott & Van Altena (John D Scott and Edward Van Altena), who were considered some of the leading slide makers of the era.
Should you wish to brush up on your lantern slide trivia, here's one article and here's another one available through archive.org, which is a great site that provides open access to complete books and articles. Should you feel like learning leisurely, the website is capable of reading the texts aloud, albeit somewhat robotically.
