The Columbia trademark from this point until the late 1950s was two overlapping circles with the Magic Notes in the left circle and a CBS microphone in the right circle. The Royal Blue labels were dropped in favor of a deep red, which caused RCA Victor to claim infringement on its famous Red Seal trademark (RCA lost the case). The blue Columbia label was retained for its classical music Columbia Masterworks Records series until it was later changed to a green label before switching to a gray label in the late 1950s, and then to the bronze that is familiar to owners of Columbia/CBS classical and Broadway albums. Columbia Phonograph Company of Canada did not survive the Great Depression, so CBS made a distribution deal with Sparton Records in 1939 to release Columbia records in Canada under the Columbia name.
