Here's my Benz auto for comparison
Been collecting Black Sox related items for about 20 years now (not long compared to many other folks). No doubt that Benz is legit...was a little on the high end as far as price goes for him, but it was a GPC which usually gets a bump in value.
As far as autographs go Ive been lucky in nabbing some tough 1919 Sox guys (Wilkinson, Ragan, Gleason) but have hit the availability wall now. I have 19 (including a Mrs Joe Jackson and not including a Risberg Im having authenticated) different 1919 Sox. Plus 5 possible Phantom players/spring training members (Bruno Haas, Ed Tabor, Bill Stewart, Roy Hansen, Fred Henry)
Been beating the bushes trying to shake loose the toughies but no luck yet (I dont think I have ever in my life even seen an example of Win Noyes by the way)!
Good luck with the collecting, I have many doubles of the easier guys if needed.
