Growing up in New York City, of course I learned about how my home town had originally been purchased for 24 bucks worth of beads. But it never before occurred to me that there might exist an actual bill of sale, or at least a written accounting of this transaction. But apparently there is! And it's currently on display along with other historical documents and paintings of the birth of New York (then New Amsterdam), at the Rijksmuseum in Amsterdam!
But fear not, New Yorkers, when the exhibit at the Rijksmuseum closes, it will travel to the South Street Seaport where you should go check it out!
