This is another review (like my previous review of prints of Leonardo DaVinci here https://youtu.be/WpXTFB9hK8g) where I guide you through why I buy books at yard sales, recycled book stores, etc. that are inexpensive and have great classical prints for me to study. Sometimes I just look at the drawings, and other times I actually copy them- trying to get the image accurate line-by-line so that I can study a master’s technique. Other times I put my spin on the same drawing, not worrying about copying their lines exactly.
