Ben Welden was a very recognizable character actor in many movies from the 1930s, and on tv shows from the 1950s, into the 1960s. He was short and bald, and usually played tough guys and street hoodlums, dramatically as well as comically.
When I wrote him in 1985, he was a resident of the Motion Picture Country Home in Woodland Hills, California. I sent him a typical portrait pose, and he promptly inscribed and returned it.
Here is a color still scene of Mr. Welden with George Reeves, from an episode of tv's "Adventures of Superman".
