Extremely Rare Pro Set Lud Denny Promo 338. Rumors say there was only one or two sheets of 90 cards printed. I have no clue, just the rumor. I worked for a color lab that did the photo work prior to printing. We were given cards at Christmas or other functions. I met Lud and his daughter or wife a few times. I am throwing in other stuff to show authenticity and they all deserve to go together. 2 Santa Cards, one Pro Set, one Parkhurst (hockey cards of Pro Set). 2 original final photo approvals prior to card printing and The Pro Set Gazette, the company magazine. All these also very rare.
