The Colophon, subtitled A Book Collectors' Quarterly or A quarterly for booklovers, was a limited edition quarterly periodical begun late in 1929 and continuing in various guises until 1950. It was the brainchild of Elmer Adler (1884–1962), founder of Pynson Printers of New York City. His idea was that various printers around the world would be willing to contribute their time and expertise to produce signatures (articles) using their own choice of papers, typography and illustration. These articles would then be bound together in boards by Pynson Printers and marketed to 2,000 subscribers.
