I've been looking in a paperback book, 500 Self Portraits, a Phaedon Book I ordered from Amazon. Since I want to practice drawing a lot of different faces with vastly different features, I figured I could find them in this book. So far, I've drawn two. This is Perugino from page 49. He included a self portrait in a fresco in the Sistine Chapel (1450-1523) Here's his pic.
