You want to see how much it's going for now? Brace yourself!
Whoa! I'm not a "believer", but I've always been fascinated by divination of all sorts and collect associated memorabilia. Most of the items are things that friends and acquaintances who know of my interest have given me over the years. Among the dozen tarot decks in my collection is the Greenwood deck, and I seem to remember having a book to go with it - although I don't know where it is. If I can find it I'm really tempted to put it up on ebay!
Back in college (during the Triassic age) I did readings to amuse my friends and pick up girls (well, try to, anyway). I always used the Aquarian deck that a Wiccan friend gave me in the mid-70s because I liked the art best. Years later I ran a D&D campaign using these same cards rather than dice... LOL... Ah the good old days.
