My husband used to be fond of milk glass, so I bought this for him. He then informed me that he's, "kind of over it". Men. Anyway, I tend to use tins for storage of baked goods, or a crockery jar if required so I suspect this will be used as a vase for tall flowers. How do you get, "over" milk glass? I should think you either like it or not.
Similar jars on etsy place them in the 70's, but I don't remember anything like this. To me, something about the metallic paint on the leaves, and the overall shape of the jar would place it earlier, but I'm not an expert on this sort of thing. I would guess many of the sellers on etsy are not either. I'm not obsessed with knowing the history and age of the things I collect, so it isn't an issue personally.
