Featured De Lutèce Glass Vases

Have these two vases and looking for some info and value. Found a similar piece at the Art Institute of Chicago.

Thanks!

I tried French Ebay, and no joy.

 

I do see similarities but not enough to definitively say they are the same. This is not glass that I am familiar with so hate to tell you anything further. I am also not finding other comparables. Wait to see what others have to say.

 

The signature is exactly the same on the Museum piece and ours however they are different in that they are painted on and not copied it appears. It's weird that I couldn't find anything on that artist.

 

I looked long and hard too. Sometimes a museum will get an entire collection as a donation.
