Manny Stallman was yet another of the journeyman comic book artists whose name usually provokes a "...Manny Who-man?" from comic book fans. Stallman was born in 1927, and was working in comics as a teen.
This "Young Robinhood" splash page from Boy Comics #13 (I showed you the Crimebuster story from the same issue last Sunday) is very crude. It was published in 1943. I estimate it was done when Stallman was 15 or 16 and it looks it.*
But Stallman went on to a career in comics and did a lot of them. He often worked as a team with John Giunta, who inked the really creepy "The King is Dead" in Witches Tales #50. This black and white version came from the 1991 reprint in Silver Scream #2. I'm not sure if Giunta helped Stallman on these other two stories. "Monkey Face" is from Astonishing #26. It's signed "S.L.", which probably doesn't mean Stan Lee, who would never miss a chance to put his full name on anything, but Stallman and an as yet unidentified inker whose name starts with "L." "Swap Shop" is from Marvel Tales #141. Stallman spent his last years in the field doing things like the giveaway Big Boy Comics, the circulation of which put his artwork in front of many more readers than the average comic book.
Stallman died in 1997.
*I can't show you the "Young Robinhood" story because I'm missing the last two pages.
