This illustration for Crowds of Creatures, published in 1964, is typical of the book illustrations of British artist Cecil Mary Leslie. Leslie began illustrating children's books in the 1930s, but was also known as an aquatint engraver and painter of portraits and still-life. She worked mainly in pen and ink, but as in this image, she used watercolours, crayon or chalk to add texture and provide highlights. She always drew from life and her illustrations were well researched.
