BACKGROUND:

The stamp art’s colorful digital illustration shows the lighting of the hanukiah on the last evening of Hanukkah. Artist Jing Jing Tsong chose her colors intentionally to evoke Hanukkah traditions as seen through the eyes of children.

The darker blue colors in the background symbolize winter, while the brightly colored flaming candles reflect the spirit and warmth of sharing the holiday traditions.

The Hanukkah stamp is being issued as a Forever stamp in a pane of 20. This Forever stamp will always be equal in value to the current First-Class Mail 1-ounce price.
Pre-orders for the Hanukkah stamp can be placed online at usps.com and by phone at 800-STAMP24 (800-782-6724).
