Billionaire Paul Allen shows off a bit of his (reputedly terrific) art collection in a show at his Experience Music Project in Seattle. “Allen’s $250 million museum could use the sales boost. Since opening in 2000, annual visits have dropped from a peak of 531,000 to 378,000 last year. Advance ticket sales for the $8 art show have been “brisk”. Entrance to the entire museum is $33.”
