Playing a rare 1930s RCA Victor 33⅓ RPM Program Transcription record

A look at and listen to a RCA Victor Program Transcription record, which was the first long-playing 33⅓ RPM format introduced to the public in 1931, but was stymied by the Great Depression, an early vinyl formulation that wore out quickly, and sound quality inferior to 78 RPM records of the day. The format was discontinued in 1933, but some of the Program Transcription records remained in RCA Victor's catalog until 1939.

Note that this was not actually the first long-playing record format; that was Pathé's giant 20-inch, 60 RPM Theatre Disc of 1913:
