Early Hupp Motor Car Co. brass trim bezel with car number. I believe this goes on the dash around the speedometer. Probably teens era. Nice shape. See pictures. Feel free to ask questions. No reserve. 

Measures around 3-15/16 inches diameter and around 3-1/8 inches inside diameter.

I am just starting to list a bunch of early automotive accessories from a great collection. Keep an eye on my upcoming auctions. All listings with the green background are no reserve auction and start at $0.99.
