Standard Guide To Collecting Autographs by Mark Allen Baker (1999, Paperback)

I just recently purchased this book, my first autographs guide. It's 10 years old but somewhat useful for tips, example autographs, and pricing. However, most example autographs are rare ones which I will never own and I don't think most people will. I was hoping for more common autograph examples. And pricing is 10 years old but interesting to see. I bought the book because I read it's the "standard" guide. The buying tips are helpful. I'll keep the book because it was inexpensive. I also bought a different, new, current guide which is more useful for pricing.
