Hermetic Library Fellow T Polyphilus reviews 50 Secrets of Magic Craftsmanship by Salvador Dalí, trans. Haakon M Chevalier.

This book on magical methods was justifiably recommended by O.T.O. Frater Superior Hymenaeus Beta for the study of Thelemic occultists. Although many of the secrets concern pigments and paintings, the most important of them have to do with perception, imagination, and discipline, and will be useful in any art, including sorcery. 

The economical Dover edition even retains the original color plates, moving them to the inside covers; and of course the book is full of wonderful black and white illustrations by the author.
