Green Man arrived today!
Wow! Thank all of you folks--I'm new to this group, but am deeply appreciative that so many of you have been so generous with your time, opinions, and expertise!
Thank you, Elven, Catlin, and WolfSpirit for your recent replies. I am heartened to learn that the deck is available in Europe and Australia. My Green Man Tree Oracle arrived today, and I couldn't be happier with it! Were these simply "postcards", I'd be satisified with my purchase. The art is fantastic! As Elven mentioned, it would make a great gift for friends. After seeing the boxed set--beautifully packaged in a hard box with a holly Green Man on the cover-- I agree, and plan to act similarly.
As WolfSpirit stated, it is a wonderful reference for tree correspondences. I would also recommend the book, "Celtic Tree Mysteries: Practical Druid Magic & Divination" by Stephen Blamires, as a good guide to the Celtic Tree Alphabet and Ogham--if you want to go further.
