This is a vodka cup purchased in the Soviet Union (Russia) in the 1970s. It is a handicraft from Leningrad, and according to overseas auction sites, the materials are enamel and brass. A hallmark can be seen on the bottom. Please check the photos. It was last used about 40 years ago and has been stored in a cupboard for many years. Some of the enamel has peeled off, and the brass parts are also generally discolored. There is also a slight distortion. As it is quite old, please check the photos for details before considering a purchase.
