Basel, Switzerland's third most populous city, boasts the highest concentration of museums and the oldest public art collection in the world. Each year in June, the city also plays host to the largest and most influential art fair in the world. The documentary ART BASEL: A PORTRAIT offers viewers a glimpse of the city, the attendees and the art of the famous fair while tracing its 40-year history. The brainchild of three Basel gallerists, the original Art Basel event launched in 1970, attracting 90 galleries from 10 countries to the small, picturesque Swiss city. Art Basel has grown internationally and now stages three premier international arts shows, providing a platform for artists and gallerists from all over the globe.
