3.5 x 4.5. That'll work, thanks!
I read this on Tarot Passages about why there are less court cards in this deck:
"Maxwell gives the following reasons for his change: "This reflects the tradition which has prevailed in playing cards, and also allows each one to clearly represent one zodiac sign." He further buttresses this argument by saying: "It is worth remembering that some early Tarot decks numbered 62 cards and the Florentine Tarot contained ninety-seven." It also allows him to make his numerological system fit. Numerically speaking, the key numbers for Maxwell's system are 3 and 7. 52 Minor Arcana reduce to 7, whereas 56 reduce to a messy 11 or 2. Maxwell was wise enough to recognize that some would find this change "unacceptable". I leave this for you to decide on your own, just be aware that there are no Pages in this deck. The remaining court cards are King, Queen and Knave."
