A photograph shows white tourists interacting with an African child who was part of a zoo-like "Congo village" exhibition at the Expo '58 world's fair in Brussels, Belgium.
However, the exhibition wasn't billed or advertised as a "human zoo" (the term is mostly used by critics to point out the inhumanity and racism of such displays), nor were the Congolese people who populated the mock village kept confined there or forced to participate against their will.
