Yes, it is Chester Gould. DICK TRACY started in 1931 as an angry, crime-busting strip that reminds one of the Charles Bronson DEATH WISH and Clint Eastwood DIRTY HARRY movies. The bad guys were mean and heartless and grotesque (Flattop and the Brow and Pruneface, ick) and they got what they deserved when Tracy plugged them.
By the late 1960s, though, the strip had gone all weird. It was about trips to the Moon (which was inhabited) in magnetic garbage cans. "The nation that controls magnetism will rule the world!" we were told. Then there were characters like B.O. Plenty (the name standing for Body Odor), Gravel Gertie and more. Odd strip.
