What's really interesting about the below Lou Gehrig signed jersey authenticated by Chris Morales, Forensic Investigator, is the fact that it was signed over 70 years ago with a fountain pen and yet there is no sign of bleeding, etc. Amazing. I would think that a "Forensic Investigator" would ask that question immediately upon "forensic examination."
