The Wall Street Journal has a piece on the art displayed in the Obama White House. Apparently for the first time ever, there's a painting made in Los Angeles: Ed Ruscha's 1983 I Think I'll, on loan from the National Gallery. (There's also a Diebenkorn, but it's from the Berkeley series.)
News to me: Hillary Clinton trashed the Henry Ossawa Tanner market. As First Lady, she bought a Tanner landscape from the artist's family for the bargain price of $100,000. Similar Tanners were selling for around a million. The White House purchase got tons of publicity, and the below-market price sent the value of Tanners plummeting.
