Hi garmonbozia,
there is two versions of the deck now. The mass produced deck made by U.S. Games and another publisher are available in many shops online and offline. I can see it on Amazon now, it came out a few months ago.
Last November the special edition came out directly from him and self-published. It has the same cards but is a collectors edition with some differences to make it unique and it's signed and numbered. It also came with a lovely bag and a pdf, but no box or booklet like the mass produced version.
I noticed on his website you can buy a box and a reading cloth for the Kipper and if you buy both, he will throw in a free deck. You cannot buy the limited edition anymore itself, unless you find someone selling theirs. It might be worth sending him a message on his website if you want the one from his website to check it is his limited edition self published version. The Box is $45 and the Reading Cloth is $65 to give you an idea of cost.
