Companions of the Moxon Chappel.

The Companions of the Moxon Chappel is a group of private printers, active in the San Francisco Bay Area. They meet occasionally to socialize and critique each other's work. Established in 1957 by a few private printers of the Stanford University area, the Moxon Chappel took its name from Joseph Moxon, author of Mechanick Exercises, the first book published in England (in 1683) regarding the printing craft. Their goals included sharing mutual interest and enjoyment in printing, exchanging techniques, ideas, and materials, and to "encourage cooperative effort in the production of non-commercial projects in the graphic arts."
