It took me a couple of decades before I was able to see the origin story of Amazing Man, and I guess those panels are thrilling. (I was impressionable in those days.)
Bill Everett, who created, wrote and drew this origin story, moved on after a while. Centaur, the publisher of Amazing Man, went out of business, and Everett went on to other comic book character, including Sub-Mariner.
Everett died young, but in his time he was a “thrilling” good artist, just as that long ago comics fan claimed.
*The letter writer's name I don't remember. It was a long, very long time ago.
