Dinah Dryhurst illustrated a special edition of Black Beauty printed for the National Trust. I bought it years ago when my daughter was very small, thinking it would be a lovely thing for her to have as she grew up. Needless to say, she has not read it. I did start reading it to her, but she lost interest relatively quickly, which is more likely to be a comment on my reading aloud ability than on the book.
Dinah Dryhurst was born in Sydney, and went to the National Art School there. She moved to England, where she has illustrated several children's books, including The Railway Children and Little Women.
There are 30 colour illustrations for this edition, and 23 line drawings. Dinah Dryhurst is not the most natural painter of horses I've ever seen; she's definitely better at figures. The landscapes, however, are particularly luscious.
