One Panel #832: Turn Around, and...

From PT Boat: "The Trail of the Mako Shark" by André LeBlanc, Military Comics #18 (April 1943)

An amazing sight from a little-known war strip, prefiguring Robert Kanigher and Joe Kubert's Capt. Storm stories in the 60s, starring Ensigns Perry Tobias and Paul Harvey. Imagine doing some deep sea diving and seeing this! Well, I'm happy I did through the magic of comics.
