The Sign Painting Project came into being between 1993 and 1997 through a collaboration between Francis Alÿs and professional billboard-painters from Mexico City, particularly Rotulistas Juan Garcia, Enrique Huerta and Emilio Rivera. Alÿs brought the billboard-painters some of his small-format oil paintings and asked them if they would copy and enlarge these motifs. Today the resulting paintings are scattered throughout the world. This book presents the grand scale and multifaceted motifs of the Sign Painting Project for the first time.
