Is that 2nd one by Tom Otterness? It reminds me of the sculpture outside the Federal Courthouse in downtown LA: https://www.google.com/search?q=los+angeles+federal+court+"the+new+world"+sculpture&tbm=isch
I love Otterness. His stuff is all over unexpected places in NYC - the 14th street subway station, and the Cathedral of St. John the Divine.
The first photo looks like SFMOMA, but the coordinates are off. Is that right?
