Since these instructions have that later (cleaned up) name, I think this stock is from the late 1980's. But that is just a guess.
Whatever the dating of this routine and props, the routine is solid gold, and still plays great today, for the right audience. It is a little risque. Not much, but a little. But I would say that only the ultra-prudish would find any offense in it. If the original name (Paul's E-ASS-P trick does not offend you, then the routine will not offend you. If it does offend you, well, yeah, maybe this one is not for you!)
Back when I bought my set of these in 1980, the cards I received were gimmicked as necessary for the routine. But I guess when Paul had to change the name, he also decided to stop gimmicking the cards, so he has added to the instruction sheet that you need to do this yourself, and gives you the instructions to do it. (It's easy, and will take about 5 minutes.)
Comes with the five ESP cards (red backed Aviator bridge), and detailed instructions for the killer funny routine, including gags and patter.
New old dealer inventory, brand new, unused, even though the stock is about 30 years old.
