Les Hommes Noirs (The Dark Men), by French Art Nouveau artists Emilé Gallé and Victor Prouve, c. 1900, made in Nancy, France.
Considered one of 
Gallé’s “talking vases” because of the two inscriptions on the vase (translated as): Dark men, where do you come from?  ~and~ We come from beneath the earth.

Acid-Etched Vase: glass, copper, and stain.
