If we're being honest, I don't typically pay too much attention to the stamps I use when mailing something. As long as the postage is correct, I'm good to go and into the mail the item goes. But there is such a variety of stamps available, I've seen hearts for weddings, and snowflakes in the winter, and some people have entire collections of stamps. Well, stamp collectors and Halloween enthusiasts get ready, because the U.S. Postal Service is issuing a Halloween stamp!
