Anyway, elsewhere in the magazine I saw a neat little sidebar - the peace symbol is fifty years old this year - it was invented in 1958 by a British artist named Gerald Holtom.

Originally it was meant to be a logo for Nuclear Disarmament - the design combines the letters 'N' and 'D' in semaphore.

They say that you learn something new every day, so we got that one out of the way early today ...
