In 1963, Jerry Gretzinger (b. in 1942, lives and works in Mapple City, U.S.A.) drew the first element of the map to an imaginary world. Each day, the drawing was added to, expanding this world and mapping out the features of an unknown land with the appearance of cities such as “Plaeides” and “Ukrainia.”

Fifty years later, the cartographer is still working on this same document that has since morphed into a space made up of almost three thousand A4 sheets of paper. Every morning, Jerry Gretzinger picks a card out of a pack that he himself designed. The card tells him the change he must make that day: to add a building, take away some streets or create fallow land.

The world he is creating is born of the map’s own development as the layers of paper sediment on top of one another. These transformations are documented in an inventory, acting as a memory of the successive steps in the construction and modification of this universe.
