This drawing is from the Danger Man episode, "The Contessa" (1961). This is the actor John Wyse as the character Julio. I've embellished some details here and there, glasses, background, lettering. This is the moment in the show when Julio and Francesca (played by Hazel Court) debate whether they should trust John Drake (played by Patrick McGoohan). Danger Man was a British TV show retitled Secret Agent Man for the American market. It was the precursor to The Prisoner.
