This is a page in the book "Who's Who in the Majors" that has been signed by the Iron Horse Lou Gehrig. This has been signed in a red colored graphite pencil. The signature pops like crazy because of it. Nice Lou Gehrig signatures are being scooped up right and left right now. In my opinion, Lou's autograph will become more expensive than Babe's because Lou died at such a young age. With that there are so many less Gehrig signatures because of it.
 
This book has a few other non notable signatures in it and has been authenticated by JSA.
