Prod. 2006 - Dumbo (I)
Directed by Sam Armstrong, assistant director Lloyd Richardson, layout Bob Cormack. This 2nd draft probably dated 2/26/41.
The first page says 5/26, the next pages 2/26.

"Additional character" animation by Harvey Toombs and Ed Aardal, with Mrs. Jumbo by Bill Tytla and Bill Shull.
Sam Armstrong was background painter to begin with, having created wonderful masterpieces for The Old Mill and, of course, Snow White. He also sequence-directed on Fantasia before his work on Dumbo, and on Bambi. Later he did layouts for Warner, but I have no idea why he left the studio around 41 - as he seems to not have been one of the strikers. One of the people we need to learn more about.
The Supervising Director of Dumbo was Ben Sharpsteen, who also is credited for the final sequence. One can, of course, find a lot of additional info on IMDb, as well, e.g. on the writers...
