A masterpiece by U.S. artist Jackson Pollock titled "Mural on Indian Red Ground" is being exhibited at a Tokyo museum after being kept in Iran since the 1970s.

The Tokyo National Museum of Modern Art is holding an exhibition of Pollock (1912-1956), including the work on loan from the Tehran Museum of Contemporary Art that is valued at $250 million.

That is considered the world's highest right now, exceeding that of another Pollock masterpiece, "No. 5, 1948," which was traded at about $140 million in 2006, the highest ever at the time.
