NO doubt in my mind. For me Jean Cocteau was a painter/photographer. Surely he was a multitalented artist, but in his drawings he shines. Personal, bold and typical Cocteau styled. These drawings are timeless and have at one time been published by Taschen in highly affordable, but beautiful executed publication.
But beside this great introduction to his ( erotic) drawings there are many other publications worth collecting on this artist. http://www.ftn-books.com has some of them available, but it is well worth to search for these small but excellent publications on book markets and at garage sales. Cocteau was a great and original artist.
