This is a Metlox Pottery Co. cereal bowl. The pattern is called Sculptured Zinnia, and the line is called Poppytrail.
Metlox Pottery was founded in the 1920’s, and began producing the Poppytrail Line in the 1930’s. Sculptured Zinnia was produced from 1964 to 1979. This line continued to be popular for many years, and is still very collectible today.
I have four (4) available for sale, each one individually. They are all in very good, used condition.
Take a look at the pictures, and if you have questions, please e-mail.
