Vintage Lamp with Reverse painted Glass Shade Trees Lake

  
I wish I knew more about this lovely little lamp. There is no signature anywhere.

Shade features trees and lake with the mountains in the background. Looks like it goes from summer to fall as you go around the shade. No chips or cracks on the shade.

There are a couple of light marks on the outside. I was afraid to get too aggressive to remove them as shade is frosted on the outside and they are minimal. Lamp is 15 inches tall. Shade is 7 3/4 inches wide and 6 1/2 inches tall. Top hole in shade is approx 1 5/8 inches in diameter. Has an extra long cord with on off switch on the cord. Base of lamp is an art nouveau style base.
