One of my absolute favorite annual (free!) area events is Art All Night, happening from now until 3:00 pm ET tomorrow in Trenton. If you haven't been before, I can't recommend stopping by highly enough.
Among the hundreds of paintings, sculptures, installations and displays at the Roebling Wire Works is "From The Key" by Carl Frankel, the first canvas I can think of depicting a moment in a hypothetical Penn/Princeton basketball game.
