The Last Supper, Vitruvian Man and Mona Lisa are Leonardo da Vinci's masterpieces on this set of recycled zip pockets. For Leonardo da Vinci painting was a science with many rules. The aim of painting for him was to represent the complexity of nature and of human personality. Leonardo was an illegitimate child, so he could not go to school, and he never received a formal education. He had to learn for himself what he wanted to do.
