MikeI agree you must find a card with a postmark on it and this would definitely help. I believe you will find out the date is 1908. The Cobb card states" He won a pennant for us last fall". Sounds like the first pennant to me ( referring to the 1907 season). If it was a 1910, it should have said " He has lead us to three pennants in a row" or something similiar.
