I found a fascinating collection of books on the history of bank notes around the world. Banknotenews.com is worth a look for those of you fascinated by the history of paper (and now in some places plastic) money.
“ This book follows the twisted tale of the trials of J.S.G. Boggs, an artist who creates fanciful reproductions of world currency--by hand!--and then "spends" his artwork to buy real things. You'll be amazed at the beauty of Boggs' bills, laugh at the reactions he encounters as he tries to convince shop owners to accept his creations in lieu of currency, and cry at the heavy-handed tactics employed by the Secret Service and Bank of England to put a stop to his shenanigans. Along the way you'll learn about the long history of reproducing currency in fine art, and come to question the very nature of "value" as it applies to both art and money.
