On August 20, 2005, the USPS issued a sheet of 5 stamps (Scott 3931-35) depicting five types of 1950s cars - Studebaker Starliner, Kaiser Darrin, Chevy Corvette, Nash Healey, and Ford Thunderbird.

These 5 covers are fresh, clean, uncacheted, and unaddressed.  Many people like to take FDCs like these and make their own cachet designs; if you are one of those people, this is the perfect set for you! Each is cancelled as First Day of Issue from Detroit, MI on August 20, 2005.
