Merc advert with Silverstone Grid - F1 Drivers own cars?

[Danesgate]

Hi
Some years ago, MBUK ran a magazine advert showing what the Silverstone F1 GP would look like if all of the drivers turned up in thier own (private) road cars - all had a Benz...

Does anyone have a copy of that advert or can you point me in the right direction on t'internet to find it please?

I am guessing roughly 1989-ish?

Thankyouverymuch
