Richard Serra at LACMA.
I could search for the title on this one but what is the point? His stuff is so overwhelming that no need to look for title on tiny placard but just experience by whole body. I have seen his stuff 1st time at Bilbao about 10 years ago and thought it was much bigger and longer than one in LACMA, but may be because I grew up.... The steel is look rusted but does not smitten the fingers when touch it. Beautiful surface. Another favorite of mine.
