Deco style cobalt blue chandelier from the Palmer House, Chicago?

Purchased this a couple years ago, and the "story" was that it came out of the Palmer House in Chicago after a renovation they went through in the 50's or 60's. I have tried, unsuccessfully, to authenticate that.
No matter, it is quite stunning, and the blue color is, I believe, a bit rare to find? It looks great lit, have it on a dimmer, with the 2 Fox prints which both have a lot of blue in them. If anyone would like to see a picture of it lit, let me know and I can add one or two tonight.
Thanks for looking!
