Notes:
Pages 32-33. Second Printing is pictured, and specifically is the pedigreed 'pay copy' meaning the editor used the cover to tabulate check payments to contributors on seven pages inside the book and on the cover. The list includes Carl Burgos, who was paid $128 in 1939 for his 16 pages of the Human Torch. This particular copy is now encapsulated and sold in 2023 for about 2.4 million USD.
