Not for inversion. Opened flat, the card measures 5.75 x 4.65 inches, or 14.5 x 11.8 cm. It is printed on both sides. There is a strange numbering system to this deck which the instruction card does not explain. It's shown in the box on the bottom of the card.
Court cards have only the strange numbering system.
If I knew more about this kind of magic, I would understand the various number systems. All rights reserved.
