Monsieur William Cull

Now this was quite a find: My French is hopless but I think this is a certificate issued to Mr Cull by Air France to commemorate an historic flight involving the North Pole and the date line. Isn't that a meridian line? I mention that because I think the typeface used is Adrian Frutiger's Meridien. Anyway, it was the illustration that attracted me to it when I saw it on a stall at the Porte de Clignancourt flea market in Paris.
