Bulgarian police raid uncovers potential Jackson Pollock masterpiece.

Bulgarian authorities are investigating a painting seized by police that could be a little-known work by American abstract artist Jackson Pollock. The painting was found in an apartment in Sofia in a raid last month and is believed to have been a gift to Hollywood star Lauren Bacall and held in the private collection of Romania's former dictator Nicolae Ceausescu. The painting is not listed in Pollock catalogues but is signed by the artist, and experts have concluded that its style and execution techniques are consistent with those used by Pollock from 1949 to 1950. The country will seek additional expertise to confirm its authenticity.
