Columbia Royal Blue Records

Columbia record series pressed from December 1932 through 1935. “Coated with a deep blue shellac, the records were promoted as being quieter than the previous black-colored pressings.” ¹ In addition to the eye-catching blue shellac, Columbia further denoted the series with its own "Columbia Royal Blue Records" sleeves and their own catalogues.
