Disney comics
The first Disney comics appeared in daily newspapers, syndicated by King Features with production done in-house by a Disney comic strip department at the studio. The "Mickey Mouse" daily comic strip began on January 13, 1930, featuring Mickey as an optimistic, adventure-seeking young mouse. It was initially written by Walt Disney (who early in his career had aspirations to be a comic strip creator, attempting without success to sell a strip titled "Mr. George's Wife") with art by Ub Iwerks and Win Smith. Beginning with the May 5, 1930 installment the art chores were taken up by Floyd Gottfredson (often aided by various inkers), who also either wrote or supervised the story continuities (relying on various writers to flesh out his plots). Gottfredson continued with the strip until 1975. A Sunday strip started January 10, 1932 with a topper "Silly Symphony" strip.
