A rare paper three-panel fold-out advertising flyer from November 1907 for the Indestructible Phonographic Record Co. of Albany, New York. This early recorded sound ephemera piece features bold black-and-white promotional graphics of their two-minute cylinder record boxes on one side, while the reverse side features a detailed announcement and a comprehensive mail-order catalog listing of available military band marches, minstrel selections, vaudeville specialties, and solos. The historic paper shows light aging, typical handling wear, minor toning, and small tears localized along the original factory fold creases. H 6.25", W 10.5", D 0.01". Please see photos for condition. From the Allan Koenigsberg collection.
