All white faces
I don't think the world was ever like that. it was quieter and more sociable pre-technology though the pic is set ini Manchester which was never really pre-technology since it was the cradle of the Industrial Revolution.
Plus. whenever there were fewer white people in the Americas or brown people in Europe it was neither better nor worse. Unless you were a Native American or African, in which case it was much better but far more boring.
The pic is idealised. The buses were full, the tip deck was smoky and the people ill-fed and worn out by very hard work while others sipped champagne.
