This heavy mug is called a "barrel mug" because of its resemblance to a barrel. In the Anchor Hocking catalog at the time, it was called the "Ranger Mug." It holds 310ml when filled to the brim, making it perfect for those who want a generous serving. The stable body and the bow-shaped handle are easy to hold. It has almost no signs of use and is free of scratches. There is a deterioration line in the center of the handle. This is common in vintage glassware and is not a crack. This is in excellent condition and can be confidently recommended as a gift for someone special.
