Concentric Space # 1, 1970; Oil on paper (framed); Signed and dated; 29 1/2" x 21 1/2" (sight); Provenance: Private Collection, New York

Signed and dated lower right recto. Not examined out of the frame. Framed under Plexiglas. Generally good condition overall, surface is stable. Sheet is very slightly bent at the edges in the frame. There is some extraneous material between surface of work and Plexi, particularly in area slightly right of upper center. This material does not appear to have disturbed surface or caused any issue with the piece itself. Plexiglas is scuffed in areas.
