GAR Civil War vets fife drum 60+ men

eBay seller obscuranta ( 3711) is offering item no. 290386461928 described as follows:

Here is a very nice mounted photograph, the mount measuring 11 x 14, the photo apx 7 1/2 x 9 1/2", only slight foxing on the photo and the mount, blind stamped on the bottom by the studio "Miller", and featuring between 60 and 70 men, most of whom look old enough in this early 1900s photo to be actual Civil War vets, almost all of them with the GAR insignia. This came from the life estate of a life-long collector, and is not identified at all, and is probably New York State.
