This may not immediately seem relevant to the current DamonCarltonandaPolarBear.com poster reveals but please read on and you may change your mind.
In 1979 an Englishman called Kit Williams created a jewel encrusted, golden Hare, this was the prize for the person that discovered it's location. The hare was buried in a ceramic casket on public land in the shadow of a cross on a hill in England.
The clues to the location of the hare were contained in a story, published in a book released in 1979. The story is about Jack Hare who trys to carry a treasure from the Moon to her lover the Sun, however the treasure is lost on the way and the reader of the book is left to find the location.
Apart from this being an example of a treasure hunt, it is also a forerunner of the modern web based ARG as we know it, the clues in the book took the form of 15 paintings, with an extra 16th clue being released later in a national newspaper.

There were even false clues, for example a magic square, where the numbers equated with Atomic Numbers from the Periodic Table and when the element letter abbreviations were substituted it translated to "FALSE NOUU THINK AGAIN".
The prize was claimed in 1982, but it was later revealed that the person claiming it did not solve the puzzles, he had some inside help from the former girlfriend of the creator of the game. The first people that solved the puzzle as intended, only a short time after the prize was claimed, included someone with the surname Rousseau.
It's 30 years since the book was first published and hopefully you can see the link with Masquerade and what we are currently engaged in. There is no suggestion so far that we need to go and start digging up vast tracts of countryside in search of a golden polar bear, however it may well be that there are clues in the posters to a larger prize of some description.
