An American antique, a Hazel Atlas "I Love Grandpa" mug. The smiley face is very cute. It's made of milk glass, so the color of the drink shows through slightly, which is beautiful. I purchased it at an American antique mall. How about a gift for Grandpa? It's in beautiful condition with no scratches. - Material: Milk glass - Size: Diameter 7.7cm x Depth 8.7cm Thank you for looking.
