Jimmy Thompson drew great Robotman backup comics in Star Spangled Comics and in Detective Comics in the 1940s. I've been on the lookout for Thompson Robotman stories ever since reading an enjoyable one in DC's GREATEST GOLDEN AGE STORIES EVER TOLD (bizarre title, yes). Recently, Pappy's Golden Age posted a great one from Detective 152.
Here's the only Thompson Robotman story I own--from Detective 151. I don't know who wrote it and neither does the Grand Comics Database.
Even in this era of "let's reprint everything" Thompson's Robotman probably won't be getting a collection. Neither artist or character is that famous, and for that matter Thompson didn't even create the characters; Jerry Siegel and Leo Nowak did. It isn't brilliantly weird (like Fletcher Hanks's comics). It's just imaginative, funny, and well drawn (and nicely lettered, if I may be so nerdly). Still, I hope I get to see more of these stories.
