Last night the cheque that started a legacy of lawsuits sold online for $160,000. That means in 1938 you could've brought over 1,000 Superman's for that.
As the auction itself states; "Without this [cheque] being written out by DC Comics, there would be no Superman, and thereby no Batman, Wonder Woman, Spider-Man, X-Men, and all the characters that came into existence after the concept of "the superhero" was born with Superman."
So much can be said about what this cheque represents, but I think the facts actually take a side all on their own. Don't you?
