“Neither snow nor rain nor smoky burnouts nor heavy exhaust fumes stays these couriers from the swift completion of their appointed rounds.”

OK—maybe we paraphrased a tad, but the powers-that-be at the United States Postal Service must have had octane on the brain recently—and we mean that in a good way.

The USPS has introduced a new series of first-class stamps called Muscle Cars (Forever) stamps. The set of five stamps celebrate five iconic automobiles: the 1966 Pontiac GTO, the 1967 Shelby GT-500, the 1969 Dodge Charger Daytona, the 1970 Plymouth Hemi ‘Cuda, and the 1970 Chevelle SS.

The United States Postal Service has had to make some tough decisions lately, including the cancellation of its Saturday first-class mail service beginning in August. However, we’re pretty sure the decision to put American muscle cars on stamps is a winner. Check them out above.
