Batman vs Superman

All Funny Comics #16 has Superman & Batman imposters trying to strong-arm a rival publisher into selling his superhero character.

There's an All Funny Comics #16 David Crippen ("D" Copy) Pedigree (DC, 1947) CGC FN+ 6.5 Cream to off-white pages up for auction in the 2022 August 7-8 Sunday & Monday Comic Books Select Auction #122232 at Heritage Auctions. If you've never bid at Heritage Auctions before, you can get further information, you can check out their FAQ on the bidding process and related matters. But before even that All-Star Comics #36 appearance, there's the strange and wonderful All Funny Comics #16 (cover-dated March-April 1947), which might be viewed as a weird meta commentary on the comic book industry and perhaps even DC Comics itself. In the story, a comic book publisher who owns the superhero character called "The Pink Eyebrow" is tormented into (almost) selling his character to another publisher by imposter versions of Superman, Batman, Robin, Green Arrow, and Vigilante. It's hard not to take that as a meta on DC Comics publisher Harry Donenfeld, who had an ownership interest in numerous publishers beyond DC Comics, and was known to be ruthless in getting what he wanted. Something had to give and that something was Max's patience. They then appear together briefly in the set-up to the adventure in All-Star Comics #36 (cover-dated August 1947) and more famously learn each other's secret identities in an adventure Superman #76 (cover-dated May 1952). We could go on. They had a single-panel cameo in All-Star Comics #7 in 1941.
