I have a theory. You see, my friend and pen pal Alice travels the world. She is such a kind, generous and creative person that she makes zines and packages of her journeys. Most of her focus is mail and postal themed, and so I have become the lucky recipent of many a jolly package of epistolary bits and bobs from all sorts of places. If you can't tell, I love it! Alice is the best.
My point is though, that I've started to notice something, and it's something that I can't exactly find corroboration about on this magical information land that is the Internet. All the airmail envelopes have that wonderful chevron edging and each is unique to its own country. The most striking difference is often in the color of the chevrons. What I have discovered is that the colors seem to correspond to the colors of that particular country's flag.
I didn't notice it at first because airmail envelopes from the U.S.A. and the U.K. and Australia are all red and blue; so I thought that all airmail was just red and blue. Occaisionally, I'd have a different color combonation, but I didn't put it together until Alice's recent trip to Brazil. She sent some zines of the postal uniforms there and we got to talking about why they chose certain colors over others. The airmail envelopes from Brazil are edged in green and yellow. The colors of Brazil's flag? Green, yellow and blue. Alice thinks I'm on to something and she sent me some envelopes from Mexico. They are edged in red and green just like the main colors on the Mexican flag.
I love the idea that "official" airmail envelopes are like little flags being sent by mail. I enjoy thinking that you can tell where a letter is from just from the colors on the outside edge of the envelope. What do you think of my theory? Got any other evidence to back it up? Show me your envelopes! I'm thinking Sweden should have some yellow and blue ones.
