Milton Mouse
Milton Mouse is an animated character created at Fables Studios for Paul Terry's cartoon series Aesop's Fables (later Aesop's Sound Fables). The character was introduced in 1921, and appeared in dozens of cartoon shorts through 1931. Milton often appeared alongside a girlfriend mouse, usually named Rita.
In 1929, animator John Foster redesigned Milton and Rita to look more like Mickey and Minnie Mouse, who had become very popular following the 1928 release of the Walt Disney cartoon Steamboat Willie.
Milton's new, Mickey-inspired design debuted in the cartoon A Close Call, released in 1929. Further cartoons released in 1930 included Western Whoopee, Circus Capers and The Office Boy. A lawsuit filed by Walt Disney in 1931 claiming copyright infringement put a stop to Milton's appearances.
