"A forensic scientist said yesterday that a large group of paintings
discovered several years ago and thought by some to be by Jackson
Pollock included many containing paints and materials that were not
available until after the artist's death in 1956."
...... "Mr. Martin was commissioned to examine the paintings in 2005
by their owner, Alex Matter, the son of Herbert and Mercedes Matter,
artists who were friends of Pollock's. Mr. Matter has said he found
the paintings, made in Pollock's signature drip style, in 2002 or 2003
in a Long Island storage container that had belonged to his father."
