[OK, OK, I should include some actual information here. Smilin' Jack was a newspaper comic strip, created by Zack Mosley, that ran for 40 years. The character had a radio show in 1939, a movie serial in 1943, and this comic book in 1944.
But you still want to smack that smug puss, don't you?]
From Four Color #36 (1944)
