The philosophy of collecting....

Talking of philosophers : "Je collecte, donc je suis" said Descartes, but which was the REAL title of his book? (Spot the difference between the two stamps.) A clue, most French philosophers were LEFT-wing, weren't they? French intellectuals quickly spotted the error - a national crisis, one of the many in the 1930s, the Post Office had "tombé dans la merde". The offending stamps were quickly withdrawn and a correctly titled version appeared. All was not lost, the publicity did quite a lot to encourage collecting, and philatelists rushed to get both versions.

And a few more thoughts about philately......
