Following my post on the Three Little Pigs fight tuberculosis poster from yesterday, Jim Korkis sent me the following email:
[I am sure you remember that Walt's older brother, Roy O. Disney, was in a veterans' hospital in Sawtelle, California (near Los Angeles) recovering from tuberculosis in 1923 when Walt burst in and told Roy that he had a contract to produce the Alice Comedies. Roy checked out of the hospital, the spot on his lung healed (although he was still weak and had to leave work early in those early years), put his savings into the Disney Brothers Studio and was never again troubled by tuberculosis.]
That is likely to be the reason why the Disneys allowed for the use of their characters in that poster. Or is there more to the story?
