Group Airmail Envelope Swap #1

Does anyone else collect airmail envelopes? I love all the variations, big or small, in their patterns. I never pass up a bundle when I see them in a thrift store.

This swap is for 5 unused airmail envelopes or aerogrammes to one partner. They should be storebought or vintage, no handmade, please. There should be no more than two of the same design, as the point of this is to see lots of different designs. But even if you get ones you already have, you can of course use them to send something else!
