This postcard, mailed in 1919, features the boulder on which Alexander Hamilton purportedly rested his head after being mortally wounded by Burr. The site depicted here is not the precise site of the duel, however. The boulder was moved from its original spot to make way for train tracks. And today, the bust of Hamilton sits upon a pedestal, with the boulder sitting behind it.（Source:https://sinclairnj.blogs.rutgers.edu/）
