This beautiful mug has clear crackle glass with a green applied handle and was made sometime during the mid 20th century. It measures approx. 5 1/4" tall. I'm not sure who the maker was. I found one similar to this one on pg. 194 of Crackle Glass from Around the World by Stan & Arlene Weitman. They can't attribute it to a maker. This glass is in excellent condition. No nicks, chips or cracks. I am happy to answer any questions you may have. Thanks for looking!!
