A $400m Van Gogh Gone With Nary a Trace

The painting, done only weeks before the artist's suicide, has not been seen in 34 years

When the hammer fell at Christie's in Manhattan on May 15, 1990, a Vincent van Gogh painting, Portrait Of Dr Gachet, set the record at the time for the most expensive work of art ever sold at auction, going to a Japanese paper magnate for US$82.5 million.

In 1998, the painting was sold privately to an undisclosed party. Since then, the trail has run cold.

While the art market thrives on secrecy and protects privacy as a matter of honor, it also employs people whose mission is to collect reliable information on who owns what. Some are auction house representatives; others are art advisers or dealers who have made a specific genre their special niche.
