I compared it to another type 2 and it is much thicker. After looking at it under a magnifying glass it appears to be two cards stuck together. The card is brittle and pretty delicate so I hate to try to separate the cards. I tried a blow dryer to heat it up just to see if it separated a little bit but it didn't make any difference.
I think I will leave it alone. I'm sure the hidden card is either Ty Cobb or Walter Johnson.
