National Allied Publications was founded by Major Malcolm Wheeler-Nicholson in 1934 to publish Fun: The Big Comic Magazine #1 (Feb. 1935), later known as New Fun and More Fun. The first American comic BOOK with solely original material rather than comic strip reprints, it was a tabloid-sized, 10-inch by 15-inch, 36-page magazine with a card-stock, non-glossy cover. Issue #6 (Oct. 1935) brought the comic-book debut of Jerry Siegel and Joe Shuster, the future creators of Superman, who began their careers with the musketeer swashbuckler "Henri Duval" and, under the pseudonyms "Leger and Reuths", the supernatural-crimefighter adventure "Doctor Occult".
