WOW !!!
Check out these Vintage mugs / tankards
The metal part is chromed, has a nude lady for the handle and a dragon in Japan
The Blue Cobalt glass can be lifted out of the chrome part
This set comes in a wooden box with a pink lining and packaging paper.
I am not sure on the exact date, however.....
The packing paper reads Ginzakan Mart Tokyo Japan
Also there is a piece of paper from the Nikkatsu Hotel...This hotel was built in 1952 right after the US ended the Occupation of Japan. I would date this set somewhere in the 1950s or 1960s
