The Tale of Peter Rabbit
Warne wanted color illustrations in The Tale of Peter Rabbit, which he called the 'bunny book'. He also suggested that they only use 32 illustrations instead of the first 42 illustrations. At first, Potter did not want to color her illustrations, but she came to realize that not coloring her illustrations would be a bad idea. She sent Warne some new color illustrations with a copy of her privately printed edition. Warne then gave these two the famous picture book artist, L. Leslie Brooke, to see what he thought about the pictures. Brooke was delighted with Potter's work. At the same time, small picture books became very popular.
