I stumbled upon something interesting while researching and writing the Spanish Grand Prix chapter. Something I hadn’t realised before. Fact is that the Spanish GP is one of the oldest Grands Prix in existence. The first one was contested in 1913, and as many as 12 races took place pre-WWII. This makes only the French, Italian, Belgian and British GPs older, and the Spanish race one of the old ‘Grandes Épeuvres’. Just thought I’d share.
You could have found this information in this wikipedia article about the Grand Prix Motor Racing.
I did read that article. But thanks for posting. Have you read part I of my story?
