The Franco-British Exhibition of 1908 is worth reading about. It was apparently a celebration of the virtues of colonialism. The Wikipedia article reports that:
Press reports commented on the "surprising cleanliness" of the Irish, while readers were reminded that the Senegalese were "cleaner than they looked."
It was also advertised by way of limericks, surprisingly racy for the time:
A maiden of coy disposition,Met her fate at the Bush Exhibition,When his great love he told her,Placed her head on his shoulder,And enjoyed the happier position.
In an Anglo-French section one night,A Youth met a Maiden, gay and bright,But her idea of pleasure,Was of such boundless measure,He left with heart heavy – purse light.
