As a leader of the American Pop Art movement, Andy Warhol saw his works, together with his image, given wide media coverage. But aside from this coverage, what about Warhol’s own advertising genius, his gift for creating brilliant posters to sell products or promote causes and events? The collector and art historian Paul Maréchal reveals another aspect of the artist’s graphic design work. This time, he has chosen to share with the public his collection of fifty posters and almost a thousand illustrations found in 400 magazine. The exhibition will be accompanied by two catalogues raisonnés, the outcome of intensive research. Paul Maréchal gives us an overview of the show.
