I found at an estate sale an unusual milk bottle and bought it just because it was so unique. It is 18 inches tall. The glass is about half an inch thick. And it weighs 8.4 pounds. There are vey little markings on it. There is no color, only clear glass. Any markings are raised glass and are as such- on the bottom a star, on one side a cow, and on the other the word milk with a star and under that 1890. I cant find anything about this. Does anyone know what the origin could be. My husband said maybe it was a prop or something.......however it is very heavy glass. Thanks. Im getting tired of searching for info on it, if anyone has any ideas let me know!
