This 1962 DC PSA is one I didn't recall so I'm thinking that maybe it wasn't printed in all the titles. I'm drawing a blank on the artist although I recognize the style of the kids in the "What th'..." panel. The dark haired one strongly resembles the kid in the famous "steak on the black eye" PSA from a few years later. The SUPERMAN figures, particularly the full body shot, seem traced from some standardized style sheet of the time so it's hard to tell from them. Steve? Sam?
