A McDonald's breakfast set mug made by Hazel Atlas from the 1960s to 70s. The bottom is stamped with B-5. Fire King mugs with the same print were also manufactured during the same period. Hazel Atlas milk glass tableware is characterized by its slightly matte and thick form compared to Fire King and Federal. Purchased at an antique mall in the US, it appears to be unused, in good condition with no stains on the glossy bottom. There is some paint transfer on the bottom left of photo ⑦b, but like the kneading wrinkles, it is from the time of manufacture. We ask for your understanding as this is a characteristic of milk glass products. - Size: Approximately 7.5cm in diameter, approximately 8.5cm in height - Type: Household goods - Material: Milk glass Thank you for viewing. #Vintage #AmericanGoods #Mug #McDonalds #FireKing #MilkGlass #Federal
