Here's a website that offers rare and/or unique items, for sale. For example: Enron, Worldcom, Global Crossing stock certificates, etc.
Some of these items may be good conversation starters to hang on the wall in your office or as gifts to send to clients and prospects.
Of course, when I came to the "fraud and scandal" section of this website, I immediately thought of these boards!
Look on EBay, there allot cheaper. I have a very nice "Pennsylvania Railroad Company" stock certificate matted and framed hanging on my wall. I bought 10 certificates for about $11 + shipping.
