The National Postal Museum’s Halloween program offers hands-on art, seasonal stories and a museum-wide costume parade. Smithsonian’s listing places the event on October 31 from 11 a.m. to 3 p.m. Eastern, with free admission to the program.

Follow the yellow-brick connection

Educators from the National Museum of African American History and Culture will explore connections between The Wizard of Oz and The Wiz. The planned station pairs a Wizard of Oz stamp with costumes from the NMAAHC collection, then invites children to design a costume for Toto.

Go to the correct museum

Despite the NMAAHC educators’ involvement, this event takes place at the National Postal Museum, at 2 Massachusetts Avenue NE in Washington. That distinction is worth saving with the invitation.

Make a simple plan

Costumes are encouraged. Check the Smithsonian event page for updates before heading out, and choose an arrival time that leaves space for the activities your family wants to try. The published window describes the program, not a promise that every activity is available at every moment.
