Background: This pane of 16 Forever stamps features eight unique designs illustrating a variety of backyard games — badminton, bocce, cornhole, croquet, flying disc, horseshoes, tetherball and a variation on pick-up baseball. Each design emphasizes the movement of the game pieces, giving a dynamic quality to the artwork. Using a simplified style that evokes the nostalgic feeling of playing backyard games as a child, illustrator Mick Wiggins created the digital illustrations with the iconography of vintage sporting posters in mind.

Greg Breeding was the art director. Mike Ryan designed the stamps with original artwork by Wiggins.

The Backyard Games stamps are being issued as Forever stamps. These Forever stamps are always equal in value to the current First-Class Mail one-ounce price.
