Take part in a treasure hunt at the Natural History Museum and find £1000

Magician, card master and all round mysterious man Drummond Money-Coutts has organised a treasure hunt in the Natural History Museum in London. He's carefully hidden small envelopes around the venue with £50 notes in them. However this week he's putting £1000 in to one for a lucky individual to find and keep.

So far only 3 have been found which means there's still plenty more up for grabs. Subliminal clues on his facebook page might just help reveal the answer.
