Picasso's "Head of a Woman" keeps an eye out near the train station. The sculpture was actually a collaboration between Picasso and Norwegian artist Carl Nesjar. The leaves are thinking of turning.
(Untold stories: The sculpture belongs to the John Putnam collection, in memory of a Princeton student who was a fighter pilot in WWII, including over Normandy beaches on D-Day 1944, and who died just 6 weeks after D-Day in an accident in England, age 23. The sculpture collection is credited to an "anonymous donor" - in reality, it was Putnam's younger brother, Peter, a physicist who inspired great devotion and died a janitor).
