Even if you don't, I think these are cool enough to make you want to stick one on an evelope and mail it. They're scheduled to debut at Comic-Con, a comic book and pop culture show in San Diego.
Another series came out before these, and they really crack me up. Who doesn't like Superman and Wonder Woman? I guess my friends officially are nerds, because we like to send letters in the snail mail and actually check out the stamps once they arrive.
Oh well. Enjoy the pic.
