This advert is nuts...

Given how proud British Rail was in these old vintage adverts (currently on display at Richmond Station due to some stop-start work going on that's removed years of other ads pasted on top) of serving travellers going to Gatwick (here and here) it seems bizarre that this ad is taking lumps out of short-haul flying! But the idea and execution is quite nice.

This is number 12 of these vintage British Rail posters - see number 11 here.
