Two firsts for the blog today -- first post for a comic book from October 1939, and the first issue ever released by Brookwood Publications (a company later absorbed by Harvey Comics).
This is a rare occurrence of someone else being present at the birth of a superhero.
Shock is the first superhero to work out of an office (though there is a pulp fiction precedent, with Doc Savage having his own office).
Rescuing people from suicide was an early trope of Superman comics.
Shock is not one who likes to use wrecking things, but he uses it here to comic effect.
Shock is clearly using a Leap power to navigate the canyons of the city, but it's unclear if it is Leap I, Leap II, ...
In moving cross-country, though, Shock is using a more speed-based power. We know how long it takes him to get to the Rocky Mountains, but we never learned his starting location. If it was New York City, then Shock is moving 800 MPH and must be using, at least, Race the Bullet, if not Invisibly Fast. If, however, he started in Chicago, Illinois, then Shock is only going 500 MPH, cruising speed for Race the Bullet.
West Spanish Peak. The mountain in the background even looks a little bit like West Spanish Peak, if you squint hard enough (or imagined the volcano after a diet...).
