Ann Arbor: Lightworks, 1979
11 x 27cm, unpaginated c. 32pp plus card covers. Exhibition catalogue with numerous reproductions of the various envelopes used by various artists in correspondence art including George Maciunas, Ray Johnson, Anna Banana and Ida Applebroog amongst others. Essay by Ken Friedman. The cover of the catalogue has a tiny envelope tipped onto it as issued (sans any enclosure). Very good.
