The organisers of the 1958 Brussels World Fair published several posters to advertise the event worldwide. Hundreds of thousands of copies were issued and in several (mostly eight) languages. Many of these posters often depict symbolic figures, like the fair’s logo, or its main monuments. This one is signed by the graphic designer D’Hooghe, who remains unknown. It represents the Atomium, the Fair’s flagship monument, which eventually became one of the most universally recognised symbols of Belgium’s capital city. The Atomium symbolises the hopes for modernity and progress of the post-war period and, in particular, the faith in nuclear energy.
