http://johnnyburrito.com/uglymoney.htm This is a great website for anyone (like me) interested in money that has been written on, drawn on, stamped, mutilated, or otherwise generally defaced. I myself own a $1 star note with a Betty Boop stamp on the back, a $1 with a stamp on the front, and another $1 with a message written on the front. (see attachments)
