Philadelphia, PA: Gravity Press, 1976. First edition. Oblong softcover. Features text by Larson which describes how he used a Graphic Sciences DEX 1 Teleprinter, an early fax machine, and manipulated the output to create a new form of art. An about very good copy in wrappers with creasing and wear to the corners and some other wear. Internally a clean copy and despite the flaws a solid copy of an uncommon book.
