I was very interested in what Ivo & Peter have said about "Lagny" pieces. A few years ago, in the original version of this Board, somebody raised a query about a "Lagny" cameo vase and I happened to also have one but could not find anything about the maker.
I appreciate that signatures often vary within companies but for info here's my example and views of the front and back of the vase (I suppose the front is the one with the raised Dragonfly body, but I prefer the back) ...

I bought this vase in the mid 90s (1990s
) and even the auctioneer commented "... not a lot of age to this one ...".
I did eventually get a response from other enquiries (can't locate that info right now) saying that Lagny was a modern company somewhere in or near Paris. Could it really be from the Baccarat works?
By the way, whether Cyn's lamp is Nouveau or Deco in style is something I could not say for sure but I don't think the signature of the lamp is the same as on my vase - but a clearer (non-flash) photo of the lamp signature would be useful.
