Leonardo & Raphael

The local library was having one of its book sales last weekend, so I picked up a couple of things. These were 2 books that I got for my personal art library. I've been doing a lot of drawings recently, and these 2 artists are among the best ever in the draughtsmanship department, as well as being great painters, obviously. I should be able to find some inspiration within.
