(Albers, Josef). INTERACTION OF COLOR by Josef Albers. Yale University Press, New Haven, 1963. Edition of 2000 copies, of which there were 50 signed and numbered by Albers (this NOT being one of the signed copies). Large quarto. Cloth slipcase containing text volume (cloth, 80pp.) and cloth chemise-style box with concordance to plates (wraps, 48pp) and eighty folders (13 x 10 inches, opening to 13 x 20 inches) containing the plates, each with a protective tissue to prevent offsetting of the colors. Plates are printed in as many as twenty colors, with a combination of silk-screen (serigraph), four color separation and photo-offset processes. Some browning and discoloration to the outer folders, but with the internals Fine and very fresh. Altogether a very beautiful copy of this increasingly scarce title.
