I just noticed this on the Center for Photography at Woodstock's site www.cpw.org

July 11-15 | Lothar Osterberg Photogravure in collaboration with Women's Studio Workshop.

Osterberg, IIRC used to post some gorgeous gravures on apug some time ago. When the CPW publishes the details of their catalog, I'll post here again. The workshops there are always worthwhile, although they're not as inexpensive as I wish they were.
