Rodin's 'The Thinker' and Other Sculptures
These are some sculptures from the Legion of Honor museum in San Francisco, USA. I believe there are three separate casts of The Thinker in sites around the world, one of them at this museum. It also has a outstanding Rodin collection (yes, he has some other great works, also) and some other notable sculptures from medieval to 20th century eras.
I love the very first three sculpture if I have to choose but all look great
