I think David Blaine? Weren't his Split Spades cards sold here exclusively at one point?
I bought a deck of those... and wore them down to the ground. Front pocket, constant carry, dropping cards everywhere as I learned, and learned, and learned.
If my memory is off on that, then it was Google. But I think it was David Blaine.
Either way, Happy 15th Birthday to one of the best magic companies in history. Your products have made my life (magical and otherwise) infinitely better. Here's to your next 15... and beyond.
