How long have you had it? How long have you been in direct contact with Tarot? This is not a cosmetic deck. It is a visual depiction of every aspect of life under the microscope, and methodically disssected. Everything MEANS something and almost ALL of it is intentional. It is brutally honest and a pure conduit, in the right hands under the right context... when seen with understanding. The Creators were some of the most astute and nonconventionally carnal occultists of their time - the deck reflects that explicitly.
What publication of the deck do you have?
As for the back, the artwork is part of the Magickal Tradition of the Creators. It is the synthesis of Qabalistic, Geometric, and many other systems. The main overlay is the Rose Cross in the Second Order of the Golden Dawn Tradition. It is a Rosicrucian symbol showing all the Elements, Planets, Signs of the Zodiac, and colors of visible light. Furthermore, it displays reversals so you can correct the cards for readings if you don't read reversals.
