The postal service might be going down, but at least they’re going down in a blaze of glory. The new Muscle Cars stamps are easily the most awesome way to pay a bill (outside of, you know, paying online like almost everyone). The collection of Forever stamps feature a ’69 Dodge Charger Daytona, a ’66 GTO, a 1967 Shelby GT-500 (so, so great), a 1970 Chevelle SS, and a 1970 Plymouth Hemi ‘Cuda. The art is done by Tom Fritz, and is bright and attention-grabbing. Even if they weren’t sticker stamps, they’re so drool-inducing that you wouldn’t have any trouble licking them.
