Vintage USA Vintage Mug Milk Glass 【Manufacturer】 Glasbake Glasbake 【Size】 Approximately Height...9cm, Diameter...8cm Glasbake, Raggedy Ann & Andy Mug The enduringly popular Raggedy Ann & Andy. A very cute item. This is a type without the Glasbake stamp. 【Age】 1960s~ 60's There are black spots on the bottom inside. Black spots, especially seen in milk glass (particularly antique items like Fire King), are caused by impurities mixing in during the manufacturing process and remaining as small black specks when fired at high temperatures. This is not dirt, but rather a manufacturing characteristic, similar to "streaks" or "white spots," unique to vintage items and found in most items. As a characteristic of milk glass, Please understand that manufacturing imperfections such as hairline cracks, color unevenness, white spots, and air bubbles (burst bubble marks) are considered part of the product's character.
