The Hazel Atlas Glass Company of Clarksburg, West Virginia, (early 1930s), produced many glass tableware services and much of the glass kitchenware that is now collected from the era of the 1920s and 1930s. Tumblers were produced in such abundance that the Clarksburg, West Virginia plant became known as the “World’s Famous and Biggest Tumbler Factory”. The green mixing bowl sets and the dinnerware in opaque white glass are highly collectible.
