September 30, 1944
featuring the 1944 cartoon diary of animator Irv Spence
I think that's Avery's story man Heck Allen caricatured on the left. No idea who "Dog" is.
From the March 1997 issue of Local 839's The Pegboard:
1985 Golden Award winner JERRY HATHCOCK died on March 8, 1997 at the age of eighty-four. From 1934 until his retirement in 1977, he worked as an animator, director and producer at Iwerks, Disney, Harman, UPA, Hanna-Barbera, Filmfair and Quartet.
Hathcock was a charter member of Local 839 -- one of the signers of the original petition that led to the founding of Local 839 in 1952. With his passing, only four of the original twenty-one charter members remain.
Based on previous drawings, and a couple of wild guesses, I think that the people seated around the table are, clockwise from Spence, Leo Harris, Carmen Maxwell, Joe Barbera, (possibly) Michael Lah, Bill Hanna (maybe) and Harvey Eisenberg. Better guesses are welcome, as is any information on what it was that Leo Harris did at MGM.
Some background on the invasion of Peleliu (Palau) here. There's a first person account here.
