This is a superb piece, alas I'm broke and not a Cobb collector. But I do think I can date your photo for you and give some more background to help (and perhaps boost the value of the piece):
In 1910, Cobb and Lajoie were embroiled in one of the tightest races for a batting title ever in the AL. Cobb won by a hair despite some fishy business on the part of Lajoie on the last day of the season, and for his effort he won a Chalmers "30" sportscar. Is this shot definitely an Oldsmobile? I really think that might be the car pictured in your photo premium (is anyone a car nut and can confirm this?), and in this case, this is a celebratory shot in Detroit after Cobb's victorious 1910 Batting Title. Great piece.
Edited to add: You can read about this in Charles Alexanders' great Cobb biography, recommended...
