The apron cards for JP look terrible. In fact most apron cards look terrible (including, I hate to say it, most of the custom-designed ones as well). The artists responsible for playfield, cabinet and backglass do a far better job on those than whoever typically designs the apron cards.
So I took it upon myself to design my own JP cards. The diagram used on JP's instruction card is ripped from the manual and it's downright horrible. I would have illustrated my own but I didn't think it was helpful enough to have one. So I re-wrote the instructions for clarity (and to reflect the correct rules) while I was at it.
I'm happy to share mine if anyone is interested. My pricing insert is New Zealand-centric, though, but I'd be happy to create other versions if people just let me know what their typical wording and pricing is.
It's a basic design but there's no use in going overboard, they need to complement the game, not try to be cool on their own. The black cards looks very striking blending into the black apron rather than the distracting white original cards. I should take a photo of mine in place.
