Vintage pickups are the latest American achievements to be immortalized on a U.S. Postal Service Forever stamp. Artist Chris Lyons has rendered four classic workhorses: a 1938 International Harvester D-2; a 1953 Chevrolet; and the two Fords seen here, a 1948 F-1 and a 1965 F-100. Get your set while you can; these limited-edition issues usually sell out quickly. Check them out at usps.com/stamps/pickup-trucks.htm.
