I purchased this pinback at an antique market and was wondering if anyone could identify a specific year for the issue of this pin. I believe it was made in the teens and possibly issued in the postseason in a year in which the Giants lost the Series which could limit it to 1911, 1912, 1913 or 1917. Insert on back states manufacturer is from New Jersey, so could it possibly be 1911 or 1913 when they lost to the Athletics (Philly close proximity to NJ)? Any thoughts or ideas would be much appreciated.
Mike
