In 1978 Georges Perec wrote 243 unillustrated postcard messages dedicated to his Oulipo friend Italo Calvino. Years later, British book artist and writer Linda Parr set up a project for artists around the world to respond to the messages by producing the missing images: actual postcards were sent from twenty-three countries.
These postcards are exhibited in the Reading Room of La Médiathèque until 25 July 2025.
