Mountain Dream Tarot, a beautiful, symbolic interpretation created by Bea Nettles, 1975.
I would love to locate either the book or the pack, but it doesn't appear to be available any longer. The images resonate with me quite deeply, both personally and creatively. If you happen to know where I might be able to find more information about them within the UK I would be extremely grateful!
Edit: Thanks so much to Lorraine for providing so much wonderful info & sharing links to this video...
