It appears that the idea of dollar bills stamped "Where's George?" has taken on more than just tracking the distribution of paper money. Pay a visit to http://www.cruelty.com/money/ for a collection and explanation of how paper money has become a way of "spreading the word".
"Some bills advertise political opinions. Others share highly personal messages, I suppose many of which are in-jokes. And some are probably just artistic creations."
Signing off. Until next time, I'll see ya on the Blog!
