But I've just pinned it down - he was Paddington Bear! That's why he looked so iconic. He was wearing a dark blue duffle coat and wellingtons, and he had that kind of rounded look. He had a square brown bag made of that sort of sackcloth material rather than a suitcase, but it was about right in relation to the size of his body. Admittedly, Paddington normally wears a big hat not a beany, and does not have a beard, but none the less the resemblence was striking...
The other thing I saw I will definitely not try to paint because I don't think I could do her justice, but it was a black lady with the most amazing dreadlocks, mounted on a really beautifully turned out bay horse, all slender legs and shiny. She was wearing perfect jodhpurs, formal jacket and very stylish long boots.
