One of those cartoonists was Russ Heath, who a couple years back, created an autobiographical comic strip about the experiences.
Over the past couple week, the strip has been shared widely online. Robot 6 has some background details on it:
...the comic strip (colored and lettered by Darwyn Cooke) was initially published in May 2012, in IDW’s Hero Comics 2012. (In fact, ROBOT 6 ran the comic that month.) Also, the Lichtenstein work cited in the comic, 1963’s “Whaam!,” was actually based on a panel by Irv Novick in 1962’s All-American Men of War #89, published by DC Comics — Lichtenstein lifted from Heath in 1962’s “Blam,” with a panel also from All-American Men of War #89. Same issue, different artists.Here's the strip. The Heroes Initiative is a program that helps comics creators in need.
