It's a 22 card deck that is handmade and one of the most beautiful things I have ever seen. Here is how Pierrick makes the decks:

One thing that I love about this deck is the mix of influences. I can see Conver, Dodal, Noblet, and very often Vieville, as is clear in this image of The Chariot:
These images are all from the second edition, which I believe is still available. I have a friend who was able to get the first edition, and it may be even more beautiful:
This is an expensive deck, but considering the craftsmanship that went into making it, and how huge and beautiful the images are, I'd certainly recommend it as a special, collector's tarot.
He also sells an earlier deck called the The Tarot d'Argolance, for you Wirth fans out there, (and I know there are a couple here!):
