I don't have any information on these illustrators. There is no indication in the book about which pictures were produced by each artist. I suspect that one of the two artists would have been responsible for the various informative and instructional pictures while the other did these beautiful, decorative illustrations - and there are many more. A very thorough book with information on every type of meat, fish, cheese etc as well as advice on utensils, pans, cookers and even a kitchen layout! Some of the recipes don't look too healthy to me though, and the colour photos of the dishes are enough to put you off attempting any of them!
