Portrait of a man

This is an original wood block print by American artist Leonard Baskin.  We are unsure as to the subject of this abstract portrait.  It came to us with an included poster with the same image for Baskin's show at the Boris Mirski Gallery in Boston.  In 1962.  This image does not appear in the Baskin catalog.  The image measures 11 1/2X 9 inches, pencil signed lower right, printed on a Japanese rice paper.
