Here's a 1934 Christmas Card from Fleischer Studio employee Bill Van Derveer. I know nothing about him - not sure if he was an artist or production staff.
But - the background looks familiar….
… that's because it's from the 1933 Popeye cartoon 'Seasin's Greetinks!'
Cropped version of the above frame grab approximately matching the card dimensions.
And just in time for Christmas - A visual feast courtesy of the Fleischer Studio site. Ginny Mahoney (Max Fleischer's grand daughter) notified me that the site has launched its Virtual Museum, currently highlighting Christmas. Check it out here.
