Mickey Mouse universe
In "Plane Crazy" (1929), the first produced Mickey Mouse story, Mickey is seen at a farm. In all of his early films Mickey is in a rural setting, but most commonly at a farm. This setting was succinctly presented in the first sentences of one of Mickey's first storybooks:
Topolino
In 1932 the editor Mario Nerbini decided to open a new weekly newspaper for kids, containing illustrated tales with Mickey Mouse. The first issue of "Topolino" was published on December 31, 1932: it contained Mickey's first Italian story drawn by Giove Toppi. In this story Mickey Mouse was chased by an elephant. However Nerbini hadn't correctly secured the publication rights, so when Emmanuel (Disney's representative in Italy) protested, Nerbini changed the title of the comic book into "Topo Lino" (Mouse Lino), replacing Mickey Mouse with "Topo Lino", another mouse. When Nerbini bought the publication rights from Disney and King Featured Syndacate, he changed the title back to "Topolino". Floyd Gottfredson's stories made their debut into "Topolino" #7 with a Sunday page featuring Mickey, his girlfriend Minnie Mouse, and Mickey's nephews Morty and Ferdie Fieldmouse. "Topolino" published mainly Mickey Mouse Sunday pages; the daily strips were published on the supplement to the newspaper.
