In my research, I have been aware of only 3 uncredited appearances of Errol, as himself, in the Columbia Pictures Shorts Presentation SCREEN SNAPSHOTS. The 10 minute films were popular from 1930 (with sound) to 1958.
I would like to present a screengrab of his fourth, uncredited, cameo from his approx. 10 seconds on camera.
Enjoy.
