Today’s design is a Porsche 906 taking part in an Alpine hillclimb. It’s fair to say that I like Porsches, and this is my favourite. It’s a crossover model really – the race cars that developed from this model became more and more powerful prototypes, leaving the 906 as the last model that could be used as a road car (although you’d have to be quite small and hardy!).

This one’s in the style of vintage ski posters. It’s available to buy as a print, or on clothing and other items here.
