Paul, Tom Hipschen also designed the $100 bill. At the FUN show in Florida a few years ago, just before the BEP began to release the new bills, he was in attendence. The BEP put out a large brochure explaining how the bill was produced and many of the details of the anti-contefieting features. I got a chance to talk to him & he signed one of the brochures & a bill for me. Tom has also designed a number of postage stamps, which he carries with him at all the shows he attends. I still have the brochure, but I think I spent the bill at last years convention. It may turn up & might be a "RARE" find. At the FUN show this year, the Secretary of the Treasury was there & I had her sign a sheet of $1 bills. Those I still have.
