The Sunflower Bouquet 2-ounce stamp features an array of sunflowers, irises and other small flowers priced to accommodate the weight of heavy invitations, oversize greeting cards and other mailings that require extra postage. The Sunflower Bouquet stamp is similar in design to the new Tulips Forever stamp, and the two form a natural pair. The stamp was designed by art director Ethel Kessler, with digital photography by Harold Davis.
