This postcard is of the Senegalese Village at the Franco-British Exhibition in London in 1908. It was published by Valentine & Sons. The sender wrote on the back above “Official Franco-British Exhibition” that 12 cards were sent- maybe 12 cards from this fair?
Just like any other World’s Fair, this fair was a celebration. It was a celebration of the Entente Cordiale signed by the United Kingdom and France in 1904, which addressed and solved a variety of issues between the two countries. This fair was also referred to as the White City (clearly stolen from the 1893 Columbian Exposition in Chicago :p).
The Senegalese Village was just one of many village exhibits. Approximately 150 Senegalese villagers were brought to London during the exhibition to be a part of the reproduction village and demonstrate what life in Senegal was like.
