This is an awkward but legitimate question: What does John Lennon and Freddy Mercury have in commom besides being music icons?
The answer is obvious for a handfull of stamps collectors, a.k.a, philatelists. They were both, in their respectives youths, stamp collectors.
John Lennon inherited his cousin's stamp collection when he was just 10 years old. He also collected letters received from New Zealand depicting Queen Victoria and King George VI. He drew moustaches on the stamps!
Freddy Mercury collected, between the age of 9 and 12, stamps from his native Zanzibar, as well as the British Empire.
