House of cards

Postcard exhibit

The National Postal Museum is sharing secrets.

“PostSecret: The Power of the Postcard” — the Washington, DC, museum’s newest exhibition — explores the modern narrative of mail.

More than 500 decorated postcards from around the world are on display. The cards come from “PostSecret,” an online art project that encourages people to share their confessions on anonymously mailed postcards.

Project founder Frank Warren said he hopes the exhibit “will inspire others to tell their stories, discover their secret connections to others and feel the power of a postcard.”

The exhibit will run through September 2016.
