Vintage Glass Lantern Slides, made for Curtis by Edward H. Kemp, Lantern Slides, San Francisco, California, and bearing the maker's imprint, were used by Edward Curtis in his lectures and the 1911 traveling "Musicale" production of The North American Indian.
The "Musicale" meshed Curtis' images in Glass Lantern Slides with music based on Curtis' wax-cylinder recordings done in the field and Curtis' own narration, which he delivered at each performance.
There is no data on how many sets (342 slides) of Glass Lantern Slides Curtis had made but only two complete sets of the slides are known to exist.
