This is an antique Thermos Creusa cup and saucer. I purchased it at an antique market in England about 15 years ago. It has a retro design and is a translucent white, characteristic of milk glass. The cup has tea stains and is generally yellowed, and the blue pattern on the outside is also scuffed. The saucer has been used infrequently and is in good condition. As it is an old item, I am offering it at a low price to those who understand this.
