The British-born artist and curator John Coplans organised a retrospective of Warhol’s work at the Pasadena Art Museum in 1970. “The exhibition concentrates on the serial aspects of Warhol’s art…” and this poster advertising the exhibition is based on one of Warhol’s most recognisable ‘serials’ – his Brillo-Boxes. However the recognisable white, red and blue original colour scheme has been radically altered to green, blue and yellow. Warhol created his first box sculpture in 1962, producing a three-dimensional version of Campbell’s packaging before moving on to create Kellogg’s and Del Monte boxes. They were manufactured out of plywood before being screenprinted with each design. Specifically for the Pasadena exhibition one hundred extra Brillo-Boxes were created.
