This is a colonial blue Smith Glass, “Heritage” Moon and Star sugar and creamer set.
Smith Glass marketed Moon & Star, beginning in the 1960’s, up until around 1990. However, in all the years that they sold the pattern pieces, they never owned the mold. They paid the owners, a company called Weishar, for each piece that was produced.
This set is in excellent condition. Take a look at the pictures, and if you have questions, please e-mail.
