OK. I'm a Marseilles kind of guy. AND I haven't voted. I have to admit to a lot of resistance to calling the 1JJ Swiss the best deck of all time. Nice as it would be to have a 'Marseilles' deck on the list.
While I'm confessing, let me relate my earliest experience with the 1JJ Swiss. There I was, 10 years old and visiting my grandparents at their house in Manhatten Beach. Somehow I was left on my own in the front room with nothing much to do. I went through the cupboards in the side table and discovered stacks of decks of playing cards with pretty pictures. Among them was the 1JJ Swiss. It was the first tarot deck I ever saw. I spend hours going through those cards.
Does that make it the 'best ever'?
