Ryosuke Cohen has hundreds (or maybe even thousands) of mail artists send him images year after year. He periodically collects these materials & collages them into one print. Books of these prints are then sent out to the participants. This edition that I have is numbered "63/70" so the editions are small. For mail art publications this is also quite lavish insofar as it's full color & their are stickers & other objects (such as a special mathpack) collaged on overtop the prints.
