Broome and Kubert pit Hawkman against the Human Fly Bandits in Flash Comics 100 (Oct. 48), a story which will get re-written in the Silver Age as an early Hawkman tale.
Carter and Shiera see a car driving up the side of a wall, which is enough to get them into gear as Hawkman and Hawkgirl to investigate. The car, and the man who invented it, have both been captured by villains who plot to exploit them.
Some lovely Kubert art helps carry a very simple tale. The Hawks get captured, and put into a giant thermometer as a death-trap, but escape and defeat the bad guys.
