Starting in 1913 and lasting for a little over a decade, the Santa Claus Association intercepted North Pole–bound mail and delivered presents to needy children. This exhibition focuses on the work of the charity organization as well as its founder, New York publicist John Duvall Gluck Jr.. Kids can browse actual letters to Santa and old photos of the group processing mail. You might want to reassure tots that their letters to Santa are still headed to the North Pole. Plus, the bearded fellow himself pays a visit on December 15 (2–4pm), during which time little ones can climb on his lap or, if they're feeling shy, drop a letter in the North Pole Express Mailbox. All ages.
