This is a Dansk, Fransk Collection, Blanc cup and saucer set. This company began business in 1974 as an American distributor of cookware, tableware and other home accessories, based in Mt. Kisco, NY. (Although, these were actually manufactured in Japan.) As of 2011 the brand is called just Dansk, and is a wholly owned subsidiary of the Lenox Corporation, whose headquarters is in Bristol, PA.
I have five (5) of these sets, but am selling them individually.
Each cup and saucer set is in excellent. Each cup is 3-1/4″ tall X 3-1/8″ in diameter. The saucers are 6-1/8″ in diameter.
I am attaching photos. If you have questions, please e-mail.
