Up until 31 December, the CaixaForum is offering an exhibition on the creative development of Warhol, from his initial work in graphic design through to his becoming a universal pop art icon.
Warhol used all sorts of gadgets and industrial techniques to create, such as video recordings and screen printing. The artist himself defined his mechanical production methods as comparable to a production line. Part of his genius came from his ability to capture the cult appeal of industrially produced goods from the 19th century.
The exhibition also includes a selection of essays written by experts on his work, as well as a selection of portraits of the artist, with photographs by Robert Mapplethorpe, Richard Avedon and Alberto Schommer.
