This just in from Gunnar Andreassen:
[Hi Didier !
On February 16th, 2007, you had a posting where you - and Are Myklebust - asked if anyone knew of a photo of Hazel George. As we all know, she was the studio nurse and Walt's confidant, besides being a song lyricist for the Disney Studio.
Recently I found a portrait of her, see enclosure. The quality isn't very good, I'm afraid, as it is a frame grab from a documentary film. Hans Perk posted another photo of her on his blog some time ago - and it was confirmed in a comment by Floyd Norman that it was of her. See: http://afilmla.blogspot.com/search?q=hazel+george A little strange that there are so few photos of such an important person in Walt Disney's professional and private life.
