I was fortunate enough to pick up this nice Tuxedo Ad from an offer I had submitted on ebay. What do you guys think about the signatures? They appear to have been signed in what looks like to be an old fountain pen by Matty, Cobb, Bresnahan, Alexander, Huggins, and Hoblitzell. I would like some opinions on this item as I am not sure if the signatures are real or not. Should I just get it authenticated?Any input is appreciated.<br/><br/><br/><br/><br/><br/><br/><br/>
