Peter Gunn has a light grey suit and a dark tie. He has some grey hair on the sides. He is holding an eel sandwich.

Peter Gunn is portrayed in a light grey, two-piece suit. His tie contrasts the suit, being a deep black shade knotted at the base of his neck neatly. Mr. Gunn's hair, although largely white, has patches of grey mainly dominating the sides near his ears. As an unusual detail, he is holding a sandwich, not an ordinary one, but one filled with slices of cooked eel.
