I was a huge fan of the Dillons. Leo and Diane Dillon were a husband and wife team who collaborated on artwork together. They mainly illustrated books covers including many for science fiction, fantasy books which is how I first discovered their work. Back in 1981 I bought a copy of The Art of Leo and Diane Dillion. But it’s just a thin book and of course only covers their work up to that time. I would love to find a book of their later works but I have searched over the years and there hasn’t been one published. They did so many wonderful covers. I am so disappointed that no one has ever published a comprehensive book of their work.
