The image size is 28 x 23.25-inch and it is framed in archival materials. The framed size is 33 x 27.25-inch. Created in tribute to the iconic New York art dealer Leo Castelli (1907–1999), who played a pivotal role in postwar American art’s rise to international dominance. The serigraph was one of nine prints commissioned by Castelli’s son, Jean-Christophe, for a portfolio issued in honor of the gallerist’s 90th birthday. The portfolio contains prints by Jasper Johns, Ellsworth Kelly, Joseph Kosuth, Roy Lichtenstein, Bruce Nauman, James Rosenquist, Robert Rauschenberg and Richard Serra, all of whom were represented by Castelli at various times throughout their careers. Each artist approached the tribute in a different manner.
