Drawing Head and Figure
This is a fantastic book for learning to draw people. It's from the fifties, so the styles of hair and dress are outdated and the features are more European looking, but it's still an excellent reference and I improved my skills just by practice drawing some of the figures and employing the suggested techniques. I ordered this used off Amazon for a very affordable price (less than $5) and it was so worth it. I highly recommend this to artists who want to focus on figure drawing. I'm marking it read, but I will continue to consult and work on my drawing from this book.
