Stamps with wings

I have created some stationery set designs around the 'old' idea of writing to say hello to nearest and dearest far away. Playing with distance, airmail motifs and international stamps, I wanted to make a set that reminded me of the excitement of getting snail mail from friends overseas.

In keeping with the long distance ideas in the design, I have gathered international stamps of animals with wings. I love the graphic style for Panama, Romania and Mongolia, I think I'll be hanging onto these.
mmm... Is this the beginning of a stamp collection?
