A cartoon showing two chess pieces admiring a Bridget Riley painting.
The Bridget Riley painting resembles a chess board, hence the chess pieces identify with it.
The painting is in the black and white op art style that Riley employed in the 1960s when pop art was a major genre in the contemporary art world. I believe that Riley didn’t like being labelled a pop artist, so she probably didn’t like being labelled an op artist either.
