This just in through Lars Emanuelsson, who will soon post more information about his upcoming book and the subject below on his blog about Tenggren.
[I enclose an image of Gustaf taken on a combined painting and vacation trip to Catalina Island in 1936. Documents I have copies from prove that Walt Disney actually bought a landscape painting Tenggren made 1938 on one of these trips. Rumour has it there was a conflict between the two large egos of Tenggren and Walt Disney, but maybe it wasn't so deep after all?
I'm also enclosing two images that may give a hint about why Disney chose to hire Tenggren for Snow White and the Seven Dwarfs. The first one is an illustration for "Bland Tomtar och Troll" (Among Gnomes and Trolls), a Swedish fairy tale compilation from 1924. The other one is the well known illustration from "Snow White and the Seven Dwarfs" from 1938. I think it's pretty obvious where the inspiration came from. ]
