Randy Kennedy reports in today's New York Times:
"A yearlong scientific analysis by the Harvard University Art Museums of three paintings discovered in 2003 and considered to be possible works by Jackson Pollock has found that some of the pigments used in the paints were not patented or commercially available until long after Pollock died in 1956."
The New York Sun put it on the front page. The Boston Globe story is here. And Lee Rosenbaum has lots of good coverage, including a link to the report itself. Here is an earlier post of mine on this matter.
