Untitled, 1991 (91-7 Ballantine)

"The box entered Judd's repertoire as his principal form in 1963. From the early 1970s, the motif of an open box with multiple modalities increasingly preoccupied him, as he constantly explored different materials, proportions, scales, and compositions. From 1971, works constructed from plywood were fabricated by master craftsman Peter Ballantine. A number of related works-plywood boxes with the same overall dimensions but configured differently-were executed at this time. Sixteen boxes were made for an exhibition at Heiner Friedrich's gallery, New York, in 1977"
