Evidence for submission #190603-005823-399000. This is from The New York Times, January 27, 1952. Ross Martin was the artist, not the agent, in this show.
I wish I had access to this show. However, I do not. I doubt that it still exists. If you don't want to put in general identifications for the characters, then would you consider at least removing the identification of "agent" from Ross Martin's listing for this show?
