Vintage Chinese Original Reverse Painting on Glass

This is an original art from the first half of the 20th Century. 
It shows a pretty lady looking herself in the mirror in a traditional Chinese interior. 

The scene is well painting in gouache on glass and it is in its original hardwood stained and lacquered frame with an ornate brass detail on top. 
The measurements are: 22”H (with top brass) x 14”W

There is a sticker on the back with the Art number. 

In excellent condition, no chips, cracks or scratches! Gorgeous!
