Huge, beautiful rare pair of Müller Freres frosted glass French art deco vases.  Better known for their art deco chandeliers and lamps (of which we have a few coming over the next few months), you can see here that light diffuses beautifully through the Müller Frères glass art deco vases too.
The flowers are Dahlias.
The Müller Frères Luneville signature mark is on each vase and both have a very slight amber tint in places in certain lights, I'm not sure how this shows on your screen.
In great condition, one has the tiniest of chips to the collar, I am working on removing this but it may take a little while. It can be seen in one of the photos.
These would look great on a mantelpiece, or in a window where they could really catch the light.  Where will you put them?  I'd love to see picture of them in situ once they are in use.
