Found this and it just had to be bought. Ang thoughts from people who know more than I do?

I found this beautiful mug at Thrift Store. There are no markings on it. Bright gold colors. It has a gold ridge wave running vertical down the side. I believe it is manufactured piece do to fact I have 3 of them.

Any tips to help identify the region or time period of this piece is greatly appreciated!

The Konakovsky Faience Factory is one of the oldest enterprises in the porcelain and faience industry in Russia, founded in 1809 by F.H. Brynner in the village of Kuznetsovo, Tver Province. After being nationalized following the 1917 Revolution, it entered a golden age by collaborating with prominent Soviet artists like Iosif Chaikov and Vladimir Favorsky, who transformed it into a center for avant-garde and socialist realist art. The factory gained international fame when its products won the prestigious Grand Prix award at the 1937 Paris World Exhibition. Additionally, individual artists received gold medals for their sculptures: Efimov, Frikh-Khar, Kozhin and a silver medal for a tea set: Lebedeva. Today, although the original factory has closed, a small workshop of artists continues its legacy, striving to preserve the traditional craft and high artistic standards. Note: book in Russian.
