Celebrate the 50th anniversary of an iconic role-playing game with the new Dungeons & Dragons stamps from the U.S. Postal Service.

The pane of 20 stamps features 10 different designs that highlight characters, creatures, and encounters familiar to players and the imaginative world of D&D.

The selvage features a detail of an illustration showing a party of adventurers encountering a massive green dragon amid a gold-strewn ruin. The illustration previously appeared on the box cover of the D&D Starter Set.

Below the illustration is a photograph of a gold 20-sided die above the Dungeons & Dragons logo with its distinctive ampersand formed from a fire-breathing dragon. Below the logo is a detail of a hand-drawn map of a typical dungeon, a network of caverns where D&D players might encounter monsters, traps, and treasure.

The Dungeons & Dragons stamps are being issued as Forever stamps. These Forever stamps will always be equal in value to the current First-Class Mail one-ounce rate.
