I bought this book in hard cover in New Zealand in 1972 while on holiday. It was recommended to me as the very best reference book for any one interested in learning to draw in pen and ink and I have to agree with that opinion. It is full of informative 'how to's and has some terrific examples of the art including some by the brilliant author. It, and its companion volume, "Rendering in Pencil" by the same author A Guptill are the most prized possesions in my art book library. I don't lend these to anyone. I would recommend any budding artist or illustrator to aquire both of these reference books though the pencil book does not appear in Amazon's listing and may be hard to find.
