Join the Club(s)

We love snail mail, and mysteries, and tiny treasures (obviously), and also fostering community. That’s why we host several clubs and postal swaps that celebrate all of the above. Some are free and some are paid, but we’ve crafted all of them to bring a little bit of delight to your day-to-day.

Treasure Club

Every month, score a tiny treasure from our museum's collection, delivered right to your door!

Decoder Club

A mail club where you find secret messages, unlock hidden missives, venture through digital explorations, win tiny treasures.

Treasure Club/Decoder Club Bundle

Postcard Club
