Willie Lumpkin
Willie Lumpkin left his postal job in the Midwest for the excitement of New York City. Willie faithfully delivered the mail for years when the Fantastic Four moved into his mail route. While delivering huge amounts of fan mail to the famous foursome, Willie would become friends with them, and once jokingly asked for membership because of his ability to wiggle his ears. Willie was involved in several of the Fantastic Four's adventures, and for a time dated Spider-Man's aunt, May Parker.
I put Willie in a modern USPS uniform, as opposed the the gray uniform that he wore in most of his appearances, because it looks more interesting. And it's what Stan Lee wore when he played Willie in the Fantastic Four movie, and if it's good enough for Stan, it's good enough for me.
