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 and other client labels produced by the Rex Talking Machine Corporation, such as McKinley Velvet Record, Empire, Mozart, Playerphone, Rishell and other regional and mail-order brands.
