In the latest edition of Flip online magazine, Fred Cline has written an article about his friendship with Mary and Lee Blair.

It's an interesting vision about the life of that great artists, who were already retired when Cline first met them. Both Blairs worked for Disney studios, and Mary was included on the "Disney Legends" list for her astounding concept design work. 

For those interested in learning more about Mary's work,  there's an very interesting book about her written by John Canemaker:  The Art and Flair of Mary Blair.
