Ukiyo-e Reverse Glass Painting 'Geisha with Fan', Shōwa period.

Ukiyo-e (浮世絵) is a traditional Japanese art form of woodblock illustrations that was popular from the 17th to the 19th century. The term literally means "pictures of the floating world" and reflects the everyday scenes, landscapes, famous actors, and beautiful women of that time.

Reverse glass painting is a technique where the artist applies the paint to the back of a glass panel. When you view the painting, you see the image through the glass, creating a unique and sometimes glossy effect.
