Harrach Art Deco Tango Glass Vase

I'd be very interested in hearing from anyone who has seen one of these. It is an exceptionally well made vase. You only have to look at the gradations of the concave arcs which form the body. 'Black' pedestal, blue body cased in clear, very thin glass and a lot of wear to base rim. It positively towers over my other tango glass.

It was bought in France but I'm not convinced it was made there. Recently, 2022, it has been ID'd as Harrach.
