Whistletoons

In 1942, RKO created Whistletoons, produced by Avenue Studios. The series lasted until 1972. The series is the same vein as Warner Bros.' Looney Tunes and Merrie Melodies, Disney's Silly Simphonies and Paramount's Noveltoons. Whistletoons originally produced in black-and-white, until the series produced in Technicolor in 1944.
