Awesome Shirley Avis & Co LTD Victorian Copper Wine Coaster. This stunning and heavy coaster is in very good condition from the Victorian era. A nice rolled lip and sturdy bottom make this an excellent wine coaster and a very decorative item. Put it on a table or bar, makes for an excellent conversation piece. The BT on the front is a Scottish Company called Brown & Tawse. A great item, not many around. The bottom reads Shirley Avis &Co LTD. Makers London.
