Mailboxes are everywhere.
Not only working ones that still get mail delivered in them, but also some that have been reinvented for other purposes or even as works of art. What have you seen mailboxes used for?
They may be one of our favorite Americana icons. Start noticing how many times they are in paintings, in the background in movies, or given new life working some other way.
What does their popularity mean? Maybe Americans are so fond of mail boxes because they like getting mail. Or maybe they bring fond memories because they are a symbol of everyone's home.
