This silk pictures O’Brien at the center and has his colors around the perimeter. The silk is in fine condition with bold color and virtually no staining. Approximately 36” x 36.” It has been professionally framed, but there is some damage to the border of the frame. Exceptionally rare, possibly one of a kind.
