Following a link on jean's website led me to tony's mail art blog. In French, which I can't read, it seems mostly dedicated to faux stamps and real mail art, as well as odd things sent by mail (flip flops, sardine tins). Really interesting stuff.
Due to the lack of variety of stamps for airmail letters, I often use 3 first class stamps for variety when sending mail overseas - for a small cost it adds variety for me and the recipient. I've had this idea for this particular envelope for a while.
I did not do such a good job with the address label - it is not very easy to read, so I hope it gets there.
And as usual, the back. I didn't notice Jose Ferrer on the back - this would have been a great envelope to put his stamp on.
