Fantagraphics publisher Kim Thompson, who recently released the lovely, and large, Prince Valiant Vol. 1: 1937-1938, by Hal Foster, has discovered a startling difference with one of the originally published pages: more violence!
Unlike many archival projects which scan and digitally clean up the original newspaper pages themselves (I’m thinking of the stunningly gorgeous Winsor McCay reprint books by both Sunday Press and Checker), Fantagraphics are using the colour proofs from The Syndicate. As a result, at least one of the pages contained in the book reveal a page as-originally-intended, but never published.
Prince Valiant Vol. 1: 1937-1938, by Fantagraphics, (and those McCay Nemo books) are available through your local comic book store. I own all of the above titles and if you are interested in the foundations of sequential art, with work by artists still considered masters of the medium, these are the books for you.
