Announced November 1, 2021:

Over the past six decades, pony cars have become a uniquely American obsession, bringing a youthful spirit to the automotive world. These stamps celebrate five iconic U.S. automobiles — the 1969 Ford Mustang Boss 302, the 1970 Dodge Challenger R/T, the 1969 Chevrolet Camaro Z/28, the 1967 Mercury Cougar XR-7 GT and the 1969 AMC Javelin SST. The bold and dramatic artwork, painted with oils on panel, captures the energy and mystique of pony cars. Zack Bryant designed the stamps with original art by Tom Fritz. Greg Breeding was the art director.
