I value my Upper Volta Commerical License .....number 29 I think it was.....will have to dig it out of the Attic. I flew every single one of the helicopters in the country....all three of them. Later followed by Iranian, Bermudan, Indonesian, British, and Nigerian particulars in addition to my US license. One looks like a credit card, one is still tied with string, the other comes in a very, very, very expensive white booklet, and the rest are paper or cardboard.
