The market for contemporary art is booming around the world. A new exhibition called "Moving Horizons -- the UBS Art Collection: 1960's to the Present Day" has opened at the National Art Museum of China for the National Day holidays.

UBS is one of the world's major patrons of international contemporary art.

The exhibition encompasses five decades. The works were collected between the 1960's and the present day. Approximately 150 works in the show reflect changes as local styles were drawn into the global influence.

Once, the international market in contemporary art was dominated by New York City. Artists worked almost exclusively in their home countries.

Today, artists migrate. Some divide their time between continents. The art market has multiple centers -- Beijing, New York, London, Berlin and others.

Works by Andy Warhol -- the Campbell's Soup Can in 1968 -- and Crying Girl by Roy Lichtenstein are representative of American pop art in the 1960s.

There are works like Spectrum, a collage on paper -- encapsulating the work of minimalists like Ellsworth Kelly and Frank Stella.

The 1970s ushered in a quieter aesthetic. That is represented in the exhibition by Alighiero e Boetti in his Aerei, or Planes.

In Aerie, the sky is filled with cartoon-like airplanes flying around in apparent chaos.

The work refers to various realms of human activity -- conflict, travel, leisure and work.

Photography records the physical world with seeming objectivity. This is exemplified in works like 99 cents and J street. Susan Miller's J Street project collected photos of three hundred streets in Germany.

The collective work is entitled: "Jew 2002-2005." The work is a reminder of how the Nazis nearly drove the Jews to global extinction.

The shifting center of art is demonstrated in the latter stages of the exhibition. There are photos and videos by artists from diverse backgrounds.

There are Chinese artists Xu Zhen and Cao Fei. Navin Rawanchaikul from Thailand is represented -- so is Adrian Paci from Albania. Visual art's shifting horizon has made contemporary works more diverse and fluid.

Moving Horizons --The UBS Art Collection: 1960s to the present day is open until 4 November. It's at the National Art Museum of China.
