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.
