1960's Japanese Aluminum Sake Cups

I have been collecting vintage aluminum ware from the 1960's and 1970's. The colorful anodized aluminum cups and serving pieces were very popular in the 1960's as American's embraced all forms of social activity out of doors. Perfect for gatherings, picnics, and meals on the patio, aluminum ware was unbreakable and held up to daily use. The set of six 2" cups from Japan are perfect for cold sake or sipping a cocktail made al fresco.
