Hi, does anyone know where I can get information on how to spot a fake 1910-11 M116 Sporting Life Ty Cobb card?

I attained a cards a few years ago but can't find information on how to make sure that the card is authentic.

When I examined the card, the only thing that I could find suspicious was the black light gave a light glow on certain part of the card.

I am not sure if this could be because the prior owner used a solution to clean it.

Any information is greatly appreciated. Thank you.
