Oakland Museum of California
What a great museum. Fantastic collection of art, wonderful special exhibitions, and a whole wing on the natural history of California. All of my favorite things under one roof. Too much to cover in one post, so I'll start with the art.
Image above shows Untitled (1949) by Richard Diebenkorn; below is Untitled (formerly Self-Portrait, 1945) by Clyfford Still. Both painters re-located to the San Francisco Bay area in the 1940's and became leading figures in Abstract expressionism.
