The U.S. Postal Service today unveiled a new stamp commemorating Ronald Reagan, just days after what would have been the 40th president's 100th birthday. The stamp -- affixed with the mail agency's new "Forever" price denomination -- was unveiled during a ceremony at the Ronald Reagan Presidential Library in Simi Valley, Calif. He was previously honored with stamps in 2005 and 2006.

Artist Bart Forbes of Plano, Texas painted the image, which is based on a 1985 photograph of Reagan at his Rancho del Cielo, or "The Western White House," near Santa Barbara, Calif., USPS said.
