This is a really beautiful Art Deco style pressed glass ceiling shade. Although there is no apparent branding, I have found a few more of these online, and they are normally sold as French made. In really nice condition, without chips or cracks, even at the fixture holes. The fixtures themselves appear original and are made of brass with a lovely twist effect to each chain link. One of the washers to the fixings is missing and I have replaced it but with one which is a bit too big, so I would recommend changing that. The shade is 35cm in diameter and when sat flat is 10cm deep. Definitely vintage, but I can not say for certain if it is an actual 1920s/30s item. That said it’s a wonderful item.
