I just received this photo, which I bought from Ebay. It's very intriguing. A teacher is sitting with a large group of elementary schoolkids. There are three rows of white children, and one row of black children -- which implies that they all went to the same school. In front of the teacher is a placard. The date written on it: May 11, 1886. A few other words are written too: "Emery Building, B Primary." Unfortunately, I don't know if that is enough to identify where the school actually was.
