Realizing that this card is mounted now, if it has a scorecard back, it's a W530 Pinkerton Post Card. There was a Cobb from this series up on eBay recently.
There are also T5-like cards with blank backs that have no ACC designation. They're generally thought to have been issued in the 1915-1918 time period. I had one of Hoblitzell that showed him in a Cincinnati uniform but with a Red Sox designation at the bottom (he changed teams in 1914). I doubt that these were intended to be used as post cards, as they're printed on flimsy paper and blank-backed.
