Milo Winter was American, born in 1888 and died in 1956. He produced some lovely work for children's books including Aesop's Fables, Arabian Nights, Alice in Wonderland and Gulliver's Travels.
Here are some of his pictures from Nights with Uncle Remus by Joel Chandler Harris from 1917:-
Lovely, aren't they. His fairy pictures that we've used in our new sets are also very special. Will definitely be on the lookout for more of his work.
