I recently decided to pay homage to him and his work, taking advantage of a temporarily “empty” billboard. Scanning his handwriting on the back of one of his photos, which read Days of Clear Skies, I rescaled it, printed it in vinyl, and installed on a billboard located by the entrance of the Plaza España subway stop in downtown Valencia. This intervention in the subway’s billboard became a record of the physical movements of some passers-by in the following weeks. The following images above show its state on day one, a pristine blue that worked as a kind of skylight for the public’s imaginations. After 3 weeks, the image registered all kinds of human activities: spits, scuffs, tags, and paper tears. Finally, it was covered with some fast food company’s advertisement.
