The Postal Service marked the start of spring March 20 by dedicating four Water Lilies stamps at a philatelic show in Cleveland.
In anticipation of strong consumer demand, USPS is printing a half-billion of the colorful stamps instead of 20 million to 40 million, the usual run for new stamps.
The stamps depict four classic garden water lilies — aquatic herbs that live in both temperate and tropical climates around the world. The close-up images were shot by Cindy Dyer, who offers garden photography tips on her website.
The stamps can be purchased online and at Post Offices nationwide.
