I have what appears to be an original "durant" dealer sign.It is approx. 2 1/2 ft x 3 1/5 ft,heavy guage metal. It is black w/white lettering,w/red accents. It states in large letters"Durant" then in smaller letters,"A Good Car". Under that in smaller letters states"Authorized", then "Maintenance" in lg.letters under that. The bottom left hand corner is rusted out to the bolt hole,and there is surface rust over the letters "nc" in maintenance. does anyone have any idea of what a fair value would be.
