Help identifying this lamp!

Hello, I need some info on this if anyone has any. It came out of an estate sale house and I got it from Christmas from my dad. I was on Facebook one day when I saw a picture of one similar and it got me curious. So I googled it but all google can give me is that it’s a lamp that was sold at the world’s fair in 1940ish. If anyone can tell me if it’s real or anything else about it, it would be great appreciated. Thanks!
