A fascinating trio of early acoustic-era paper ephemera that captures the fierce commercial competition of the early 1900s phonograph boom. The group includes a beautifully lithographed 1902 "New Edison Moulded Records" catalogue by the National Phonograph Company of Orange, New Jersey; a rare Record Catalogue No. 21 from The Talking Machine Co. of Chicago, Illinois, featuring the "$25 Polyphone"; and an early Edison, Columbia, and Master Records promotional flier from the Penn Phonograph Co. of Philadelphia, Pennsylvania. These items offer an incredible look at early repertoire lists, machine setups, and regional distributors from the dawn of recorded sound. Objectively, the booklets are in delicate, incomplete condition, displaying significant handling wear, corner chips, toning, and scattered staining, with the Chicago Talking Machine catalogue notably featuring heavy tape reinforcement down the center of its cover and spine split wear.
