I was a little worried when I bought this deck that the cards would be too small to properly see the artwork. But at the same time, I have small hands and find large cards impossibly difficult and awkward to handle and shuffle. When they arrived the box sure did look small! The first thing that struck me on opening them was the superb quality of the printed media: beautiful to handle and not at all like one or two of the Lo Scarabeo decks I have bought recently. They almost feel more akin to plastic than card. The finish is not exactly "glossy" but more "lustre" - it really is very attractive and made a hugely positive impression on me.
As for the detail, I have had no problems at all. Even intricate artwork like the winged horse on the helmet of the Knight of Wands is visible. This is the first time, other than black and white copies in the books Mirror of the Soul or The Crowley Tarot, that I have had a chance to physically hold & study the images in person and the beauty of the deck is really enhanced by these fine cards from US Games. I can't recommend them highly enough.
They are only a little smaller than my main reading deck (The Barbara Walker Tarot) and although I bought the Thoth Pocket Swiss mainly to study the images in more detail, their size would present me with no problems for using them as my main reading deck.
I guess if you are used to huge cards the size of dinner mats these will disappoint you. But I've always felt supersize cards six inches high are more than just a little ostentacious.
By the way, I read on the little white booklet that accompanies them that in April 1904 in Cairo Crowley received voice transmissions from the hierarchial forces. Transcribed as "The Book of the Law", amongst other things it announced changes in some of the traditional correspondances. I am thinking the 7 of Pentacles in particular, which is called "Failure" in Crowley's tarot (as well as Barbara Walker's interestingly) but mostly elsewhere is interpreted as "gaining your reward for hard work".
The more I study the tarot the more convinced I am that this is THE deck to work with.
