It looks to have seems on the shoulders stopping at the neck. It also has a small #7 on the bottom. I didn't take a pic of that, i didn't think it would even show up. I know poison bottles tended to be in the blue glass but unfortunately i don't think this is one.
Very sweet little bot !!!!!! Congrats !! Looks 1890's to 1900 to me,I dont think it is a poison,probably a sample perfume or patent med , Buuut it is the first one I've seen.
