USPS introduces muscle car themed stamps

Saturday mail service will soon be history, but according to the U.S. Postal Service, muscle cars are "forever."

Today, the USPS is introducing a new set of stamps featuring five of America’s most legendary muscle cars.

Painted by artist Tom Fritz, the stamps depict the 1969 Dodge Charger Daytona, 1966 Pontiac GTO, 1967 Shelby GT-500, 1970 Chevelle SS and the 1970 Plymouth Hemi ‘Cuda, all burning their tires like there’s no tomorrow.

And, of course, they're made in the USA.

The third in the post office’s "America on the Move" series, which previously featured sporty cars and cars with fins and chrome from the 1950’s, the self-adhesive Muscle Cars Forever stamps live up to their name, and will be good as first-class mail one-ounce rate postage for eternity, or at least as long as the USPS exists.
