If you look at the St (in the space above this line), I am arguing for Street. Doggone it, though, both that apparent numeral "2" at the begining and the actual name are "a little obscure."
Thinking out loud, that "2" couldn't possibly be an old-time cursive Q, could it. If so, then the superscript "n" **might** make sense?? Possible abbreviation for Queen __?__ Street???
