Looks like a street cover...look closely at the inscription...Massacre...in Boston! and it's from the OLD one, you know, history. Wow...that history stuff is everywhere...One of the things that I loved about my visit to Boston. Following the Freedom Trail around the city was wonderful. The fabulous architecture and delicious seafood rounded out an amazing trip. So very fortunate to "be on the lookout" for metals that matter or make a difference in the world...always looking...enjoy your adventures :}
