Then DuQuette is the book for you - he explains ALL the symbolism of every card. The geometry, golden dawn symbols, qaballa, planets, elements... This will be the book you're looking for
I just received DuQuette's book in the mail, and the very first page grabbed me. Looks like he encountered Crowley right around the time I did (~1970) Right after the first Weiser-distributed printing of the Thoth deck came out in 1969. Frater Achad also led me there. And there really WASN'T much Crowley material readily available then, until Weiser (and possibly Llewellyn but they seemed more interested in Wicca) opened the floodgates and poured out many hardbound volumes of Crowley and others, which I snapped up eagerly. They are now the core of my hermetic/qabalistic/magical library.
