If you can remember that far back, they used to put these mugs in the freezer wet and when you ordered a root beer, it came to you with ice all over the inside and out. Frosty! This is one of those mugs and is in amazing collector's condition. Authentic A& W logo, just under 6" tall and around 3" diameter. Heavy solid base. We are not finding any chips or scrapes on this mug. What a find!
