Let me preface by saying I haven't done my homework here. In my defense I have a trillion books and I am not really so sure where to start with this and I don't recall seeing anything like this in any of my books.
No markings that I could find. I am gonna guess 1910 or so as a date for this. Maybe 1915. the base glass is a kind of opal with some light blue over tone and the black is actually a dark amethyst.
Anyone have any ideas on this?
