I have a long-term interest in stamps, and have set up a collectors' exchange, here, to enable fellow collectors to buy, sell and swap or any combination of these without the fees and markups we usually have to pay. Only a few items listed so far, none hugely valuable, but I'm happy to list other people's too. If you or your friends are interested, please check it out and get in touch. I'm interested in buying collections - email if you have one.
Not one of mine, but I do find this CIA "error" amusing and appropriate.
