One of the great mysteries of Bill’s prints is that although he usually indicated the number in the print run-–and as hand-pulled prints, the editions were very small—he generally neglected to date prints.
Early in his career, dates are recorded, and late in his career when his former student and good friend Master Printer Wayne Kline printed for him, the dates re-appeared, but for most of Bill’s works in the MoFA Collection there is no visible date.
