The Musolaphone Corporation writes to Commissioner of Indian Affairs Cato Sells to invite him to a presentation of their "sound transmission" equipment and "educational talking pictures." Musolaphone informs Sells that they will be holding a voting contest of the schools in Carlisle, and the winner will receive a free installation of their equipment.
Sells encloses a pamphlet from Musolaphone describing their services and equipment to Carlisle Indian School Supervisor in Charge Oscar H. Lipps. Lipps informs Sells that Musolaphone conducted a presentation in the Carlisle YMCA that all the students and teachers attended. Assistant Commissioner E. B. Meritt informs Musolaphhone that Carlisle's students and teachers attended the presentation.
