On the "Who's Who of American Comic Books" site, Harold De Lay is listed as being an artist on Maureen Marine & Jun-Gal. The artist on The Prankster story is listed on "The Grand Comics Database" as being Leonard Starr.
For those of you who might have missed it, in response to my post, "aka Centaur Comics", The Amazing Steve points-out that "The Arrow story presented here, from Fantoman #2, is indeed a reprint from Funny Pages 2#12 (December, 1938)." See, that's what life is all about: People working together to learn more. Thanks for the info, Steve. I appreciate it.
All of today's stories were taken from scans available on goldenagecomics.co.uk. The site's been experiencing some "technical difficulties" lately, but it's still the best place to go if you enjoy reading Golden Age comic books for free. And if you have a Golden Age comic that meets the criteria of being Copyright-free ... aka "Public Domain" ... that the site doesn't have (such as about half of the "Centaur" books, for example), hundreds of people would love you & sing your praises if you decided to share it with the rest of the world.
