Keen-O-Phone Record

U.S. record label, produced by the Keen-O-Phone Co. between 1912-1914. Records were pressed in both single-sided (20000-series) and double-sided (5000-series) 10" formats. After 2 years of slow technical progress and hampered by weak sales, the label folded in early 1914. Many of the titles were subsequently re-issued on Rex Record (3) and other client labels produced by the Rex Talking Machine Corporation, such as McKinley Velvet Record, Empire (23), Mozart (3), Playerphone, Rishell and other regional and mail-order brands.
