Antique Demitasse Cups in Silverplate Bases

Antique Demitasse Cups in Silverplate Bases—cup in 1 base missing These little antique demitasse cups are so unique. They measure 2 inches wide; including handle they are are 3 inches wide. The white porcelain cups come out of the bases. The holders are silverplate with a cutout pattern that looks to me like 1920’s Art Deco design. There is one base without a cup. I have not polished the bases. Please look at all pictures and feel free to ask any questions.
