USPS Forever Stamps A Flag for All Seasons Booklet of 20

The USPS issued these Forever Stamps, A Flag for All Seasons, featuring four different stamp designs in May 2013. They are valid forever, and considered collectors items because they are no longer available for sale directly from the post office. Each stamp shows an American flag, viewed from below, flying from a pole at full staff against a background of trees that evoke one of the four seasons of the year. Artist Laura Stutzman worked with art director and stamp designer Phil Jordan on this stamp art. The stamps will always be valid for the first class, one-ounce rate.
