Intriguing bronze relief for "Boston Electric Power Co." signed Remington.
49cm 39cm
A similar relief in stone or plaster is displayed on Commonwealth Edison Electricity Substation in Chicago. (picture below).
I have no idea of provenance for this one. It has obviously been mounted on a wall.
Was it an official sign for that company or a present for an employee ? No idea.
Good patina. Nice foundry quality.
Circa 1930/1950
