"Pop" can mean many things, but it refers above all to the "culture of the greatest number". Curators, historians, art experts and contemporary artists have used the enormous popularity of Vincent van Gogh as a starting point to study and reflect upon the ways in which mass culture made its way into the work of the Dutch painter and has continued to infiltrate. Like Gustave Doré or Robert Delaunay before him, Van Gogh was interested in the objects resulting from new technologies in image reproduction in the second half of the 19th century--portfolios, decorative images and illustrated journals--and in their pictorial universe. He was inspired as much on a formal level as by the content, even when his own art turned towards the avant-garde.
