The United States Postal Service has a thing for old cars. After honoring hot rods and muscle cars with a series of Forever stamps (not to mention domestic cars of the 1950s with a variety of first-class stamps), the USPS’s latest line of Forever stamps will pay tribute to the most American vehicle of all, the pickup truck.

With artwork created by Chris Lyons, the four Forever stamps will honor the 1938 International Harvester D-2; the 1948 Ford F-1; the 1953 Chevrolet Advance-Design; and the 1965 Ford F-100. As with earlier automotive tribute stamps, the vehicles chosen are representative of a broad cross section, though some would argue that milestone vehicles were overlooked. Ford’s 1925 Model T runabout with pick-up body, considered by many to be the first factory-produced pickup (as earlier examples were generally cab chassis fitted with beds), isn’t one of the offerings, and neither is the 1955-’58 Chevrolet Cameo Carrier, arguably the first “luxury” pickup.

Finally, something stamp and car collectors can both enjoy.
