This is a Smith Glass Co. green “Moon and Star” candle holder or compote.
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.
It is in excellent condition. If you have any questions, please e-mail.
