I got this one a few years back at a yard sale out on the beach here in Florida. I just liked it as soon as I saw it. From what I have found out doing research it is one of the first Tower Root Beer Bottles. It reads "Registered, Prospect Hill Bottling Co, 1 Pint 11 oz, Somerville Mass" When I first got it I posted it on one of the Facebook groups because I didn't know about this place. It is one of my favorites.
