Vintage Erhard chrome ashtray.  Erhard & Sohne was founded in 1844 and still exists to this day.  I am unsure of the exact age of this ashtray because I could not locate another like it.  This rare ashtray is approximately 4" round and 2" tall.  The interior shows rust and the exterior chrome is pitted.  Please refer to pictures for additional condition details.  Let me know if you have any questions.
