The Photo Pack has a low-resolution colorized pic of DeShong with the Yankees, but here is an action shot from Thorne Studios at 1934 Spring Training. (Once more from RMY.)
And here is DeShong in his big year of 1936 (18-10) for Washington, shot by Conlon. (courtesy of eBay)
Can't find anything from his 1932 Athletics debut, though. Even his entry at the Pennsylvania Sports Hall of Fame shows a Yankees pic.
