The Sunday Morning piece on Tyrus Wong added a few things not mentioned in the obit posted here. Apparently, he lost his job at Disney for participating in a strike regarding the unfair treatment of animation artists by Disney and that, as well as racism, had a direct effect on how he was listed in the credits for Bambi. He then went on to work for Warner Brothers for decades.
He also designed Christmas cards for years, in order to provide well for his family, and when his daughters were kids, they'd sneakily rearrange the cards on store racks so that his were in the front. One design alone sold over a million copies, so there must have been a lot of people out there who had a Wong print (or reproduction of one) without realizing it.
The Sunday Morning piece included a lot of clips from a documentary that had been done on him by a Chinese-American filmmaker who'd noticed his name in the credits of Bambi while seeing it with her young daughter and thought it unusual that a Chinese name should show up on the credits for a Disney film from the 1930s. Wong comes across as being a funny, as well as talented, guy in the clips they used.
If anyone's interested, perhaps the piece will be available on CBS.com. I'm not sure they include Sunday Morning among their available shows, but they don't seem to leave much out in terms of current episodes.
