Born of a nightmare
Consider if Edgar Rice Burroughs had lost Tarzan to a huge corporation which made millions in profit from the character over the years, and fired Burroughs from writing his own creation. Think of Conan Doyle losing Sherlock Holmes in a similar fashion. Good thing those nightmare scenarios never happened.
Superman is an icon like those characters, yet the nightmare happened to creators Jerry Siegel and Joe Shuster. A few years after being bumped from Superman they came up with another character, Funnyman. I'm sure they knew all about the Superman lawsuit against Fawcett over Captain Marvel and their lawyers may have told them, "Make any new characters you create unlike Superman or DC will sue." Funnyman is about as un-Supermanlike as you can get.
OK, so Funnyman isn't so funny...more oddball than humorous. And if anyone other than Siegel and Shuster had come up with the character our expectations might not have been so high. But he's not all that bad, either. Unfortunately, he didn't get much time to prove anything one way or another. His self-titled comic was canceled after six issues.
The Grand Comics Database says this was drawn by Dick Ayers ? or Marvin Stein ? but those question marks mean they just aren’t sure.The story, inspired by Mark Twain's A Connecticut Yankee in King Arthur's Court is from Funnyman #4, 1948.
