PROM

Prom Records was a small independent label in Newark, New Jersey, that recorded their own studio musicians and contracted talents doing cover versions of the hits of the day.

Prom was owned by the Synthetic Plastics Company (SPC), formed by Daniel Kasen in the late 1920s as a plastic manufacturer of buttons for the garments industry and game parts for the toy industry.

After World War II, in 1949, Daniel and his brother Louis Kasen founded Peter Pan Records, operating the label under SPC from then until 1970.

Daniel and Louis Kasen owned several subsidiaries music labels including Ambassador Records, Parade, Prom, Promenade, Pirouette, Guest Star, Power Records, Diplomat, Rocking Horse, Humpty Dumpty, and Spin-O-Rama Records whose motto was "Fine records need not be expensive".
In approximately 1959 Synthetic Plastics Co. resurrected the Prom label and released the 100 series.
