The Tarot of the Mystic Spiral is a deck devoted to the "everlasting search for knowledge and wisdom is represented by the spiral", which is found in galaxies and DNA, and is an integral part of sacred geometry used in building and art.
Created by Giovanni Pelosini - art by Giuseppe Palumbo.
A few cards feature nudity, some of it bawdy like the mooning Fool, some of it neutral like the Queen of Cups, and some of it sensual in its' beauty, like The Stars. For that reason, I would not suggest it as a deck for younger folk.
