Here is a video of the NPH Playing Cards. Comes with two jokers: Two premiums , one which reads: "This is going to be a challenge. Just as a spider spins its web, I've taken a page out of Cardano's book and created a puzzle. Look upon photos and images inside this deck. You can do this - just look closely at the cards. Good luck!" The other one seems to have a solar system on it with diamonds, boxes and lines, concentric circles. I have no idea except that I enjoyed handling them.
