I can't totally help with player ID's, as I've been in the same boat for a few years since I have the same panorama. (Mine is chopped off at each end and is missing about 1/3 of the picture, but it used to belong to Nuf Ced McGreevy, so those factors offset a bit for me, but I digress.)
But I do have a couple of Boston Globe articles about the game, which do help since they list all of the players who were in attendance that day. They're attached here....
That gets you halfway there to ID'ing the guys - now we just need to figure out which is which. So I guess that earns me half the Becker card??
