One Panel #640: High Wire Wildcat

From Wildcat: "Smokey Joe's Last Fire" by Bill Finger and Irwin Hasen, Sensation Comics #8 (August 1942)

For those who think Wildcat is just a boxer, revise your opinion now! Dude is right up saving a woman from a flaming inferno by walking her across a phone line at what appears to be (from other contextualizing panels) at least 7 stories up.

Those are some TALLLLLL telephone posts.
