In 2004 the USPS issued this 2 cent stamp as the fifth design in the American Design Series. The Navajo Indians began silversmithing in the mid-1800s. The silver and turquoise squash blossom necklace on this stamp is a traditional Navajo motif. This stamp (Scott #3749) is a postage stamp that under ordinary circumstances would have been largely ignored by the vast majority of United States Postal Service customers. However, something happened in early 2006 that raised awareness of the Navajo Jewelry stamp to nearly everyone in the United States who mailed first class letters. On January 8, 2006, the USPS raised the rate for mailing a 1-ounce, first class letter from 37 cents to 39 cents. People with a supply of unused 37-cent stamps immediately descended upon their local post office in search of 2-cent "make-up" stamps that would allow them to use their 37 cent stamps.
