Lady with a bird lamp -still looking for maker

I found this at a salvation army store. Never bought anything like this in my life, but I did not hesitate to (well for $6 I did think about it for 5 minutes). It was so.... I dunno, "not supposed to be there"?. Not sure if that makes sense, but that is as close as I can come to why I picked it up.

Still looking to find a maker to get a replacement shade that would be comparable to original.

If anyone has any suggestions on books or sites to read up on it, it would be very appreciated.
