Everything in the World Was Black and White in 1951?

There was an emblem of the festival. It was a red, white and blue image of britannia's head over the top of a compass. And this emblem was everywhere at the time. It was on spoons, it was on cartoons - even in pub signs. But one place it was as well, was quite amazing. It was 604 gall stones that had been removed from a patient. They coloured them and put them in the shape of the emblem,. Then they displayed it at the festival. One patient, one patient. A out of the decade, mister smith, were only on 590 gall stones. I'm afraid we needo some more. Please drink
