Both Paula Sigman-Lowery and Jeff Kurtti sent me their take about the photo of "Wacky Walt" from Mark Sonntag's collection that I posted yesterday.

They believe that the photo might be from an RKO convention, likely held at the Hyperion Studio (The louver window awnings on the background building makes Jeff thinks that it is the Animation Building - now Shorts at Burbank - on Hyperion).

Considering that RKO became Disney's distributor in 1937, and from the look of Walt. Paula and Jeff conclude that the photo must have been taken between 1937 and 1939.
