n.p. (Chicago): s.p. (Gibson Gallery), 1973
76 x 57, black on thick white paper with four original colour photographs tipped on with a land art text below. An artist’s proof aside from only 100 hand signed and dated copies. Very slight loss to the colouration of the photographs after nearly 50 years, handling creases (hard to avoid due to the thick paper used) and some some bumping at corners and edges else VG+.
