Bill Ewald's Argus Books & Graphics carries the largest stock of antique & otherwise rare books and ephemera related to the Arts & Crafts movement that I have ever seen. I've bought a few things from him, including a few excellent type specimen books, but after browsing much of his stock that he brought to the SF A&C show this past weekend, I can't wait to see a bit more of it. Bill's shop in Sacramento closed a few years ago and now he is selling primarily via mail order and at shows and fairs. It would be difficult to find a kinder & more helpful person with the knowledge of the field that Bill has; if you are looking for something in particular, please write him an email.
