This practical grimoire was definitely used, and there is several handwritten inscriptions, including an invocation written on an extra paper and inserted in the book. No need to say most of the copies of such books of magick were burned or destroyed, and are of the utmost rarity. This early edition is of the greatest value. All modern editions are based on later counterfeit editions..
