I have been collecting glass, blindly and not so blindly, but I like quality and buy anything that is engraved to the base etc. I bought this a while back and still have no idea as to who made it or the mark.......so I plead my case to the knowledge of all the all knowing. Do you have any ideas at all. It looks like LC and a couple of dots. My feeling was it was oldish.60s, 70s. You guys have been invaluable with your help recently and I thank you most sincerely. Sue
