The World's Smallest Post Service has done it again; wowing us with this set of custom "airmail" wedding invitations, complete with a tiny fold-out map and colorful buttons for RSVPs. You can see more photos on their blog. My favorite is that she also used airmail envelopes to send the tiny missive in. Her dedication to detail meant that she hand-typed all the addresses on a Royal typewriter as well. Keep up the fine work Lea! We love your stuff and can't wait to see what you do next.
