April Fools

On 1 April 1977, the Guardian printed a seven-page feature on San Serriffe, a fictional archipelago floating in the Indian Ocean.  
  
With maps, photographs and reports by the paper’s usual writers, the feature was very credible. Aided by major companies, including Guinness, Kodak and Texaco, the elaborate San Serriffe prank included spoof advertisements to make the joke even more realistic. 
  
The joke was at the expense of a readership with patchy geographical knowledge and stereotypical views of far-off places and ‘foreigners.’ Its success in tricking a nation rests on our willingness to believe a reputable newspaper such as the Guardian.

The first page set the scene with a map of San Serriffe. The two main islands, Upper Caisse and Lower Caisse ‘grouped roughly in the shape of a semi colon’ ushered in a series of typesetting jokes.
