Vintage (68) Porsche, BMW, Mercedes, VW Dealer Brass Advertisement Key tray

Description

Very interesting believed to be an approximate 1968 Dealer tray advertisement (perhaps a key tray?) BMW, Porsche, Mercedes, and VW brass tray from the Phil Gorrdens dealership in Lansing Michigan  @ 2845 E. Saginaw Street. Does show some corrosion/patina  to the top lip not sure if it can be cleaned up. I did not want to damage the patina so left alone.  Weight is around 6 ounces and is 6 inches across
