Howard Pyle 
The Merry Adventures of Robin Hood 

Robin Hood is the archetypal English folk hero; a courteous, pious and swashbuckling outlaw of the mediæval era who, in modern versions of the legend, is famous for robbing the rich to feed the poor and fighting against injustice and tyranny. 
This is probably one of the most beautiful digital version ever made of this story, containing many gorgeous illustrations.
