I recently saw this vintage Mary Quant poster on the Antiques Roadshow and immediately though of something else.
The bus going up the slope reminded me of a similar image we've seen before on the blog and from a similar period.
Yep, its the three Four-Wheel Drive Toys pictured above which were released by Century 21 Toys in the late Sixties and were then sold by Regent Toys of London. This is an advert from a Joe 90 comic and interestingly there's no mention of Century 21.
Can you think of any other adverts of vehicles driving up slopes like this?
