Whether you're a beginner, intermediate or advanced guitarist, you'll get something out of this book. I learnt to play some of the classic blues tunes of all time from The Blues Rag. Easy to read, easy to follow, and provides good notes and instrumental breaks for most songs. The author, Happy Traum, sure knows how to play the guitar, and there's no better way to learn fingerstyle country blues guitar than from the master himself. To get the absolute most out of this book, I'd highly recommend you purchase the video that accompanies it.
