This is a lithographically printed reproduction of a sensationally fun Lichtenstein triptych he painted in 1964, produced by the Stedelijk Museum between 1966 and 1991 in over 17,000 copies on three sheets. The SMA logo appears in the lower right corners. At any rate, framed and hung side-by-side, this triptych embodies all the joy and exuberance of Pop Art at its height. Lichtenstein is now right behind Warhol as the star of art in that period. A painting of his famously sold for $95 million in 2015. This is, well, somewhat more affordable, and offers plenty of "wall power."
