Vintage mug from Vitrock, a sister series to Fire-King by Anchor Hocking, USA. Unlike Fire-King, Vitrock is characterized by its pure white, glossy opal glass, resembling porcelain. This is a "Shepherd & Sheep" design, manufactured in the 1940s-50s, featuring "Little Bo Peep," the shepherdess from the English nursery rhyme. One side depicts the shepherdess, and the other shows sheep grazing peacefully, creating a charming scene reminiscent of a picture book. The red silhouette and red band on the rim give a simple yet classic impression. It's perfect for collections, display, or as a teacup for special occasions. 【Condition】 Overall, it has a good shine and is in good vintage condition. There are slight scratches and ink unevenness on the red print from the manufacturing process. There are no chips or cracks, and the "VITROCK" stamp is on the bottom. 【Estimated Era】 1940s-1950s 【Country of Origin】 USA 【Material】 Opal glass (milk glass) 【Size】 Approximately W9.5 × Φ7.2 × H8.0cm ※The prints on milk glass products may darken or become discolored due to the reaction of metal oxides and organic pigments in the pigments with oxygen and moisture in the air.
