Antique Brass Watch Fob with Streetcar Scene

Brass watch fob, rectangular with a loop at the top for attaching to a chain. Raised relief design showing a horse-drawn streetcar on tracks with a figure (driver or passenger) beside it. Appears to be an older piece, possibly early 20th century, based on style and tarnished finish. Metal shows darkening and wear in places, with some surface scratches visible. Please check: maker or marking on back, whether it is solid brass or plated, and exact age.
