Over 60 years old, this double page advert for Champion Spark Plugs, which appeared in the July 1962 issue of the USA monthly magazine Car and Driver.
 
It  recalls the competition success of different cars on the Sebring track in 1962, including:
the Jaguar E-Type, run by Briggs Cunningham,
the Morgan +4 Super Sports, driven by Al Rogers
the Fiat Abarth, also run by the Cunningham team
the factory entered OSCA
the Wyllie-Black Chevrolet Corvette
 
On the rear of these are full page adverts for the Chevrolet Corvair Monza Convertible and the Studebaker Avanti.
 
Great for framing.
