Engraving plate and prints realized in situ at BAC Bâtiment d'art contemporain - Le commun in Geneva, within the collective exposure [terra incognita], conceived by the Geneva engraving studio. The matrix is engraved on a board of OSB, identical to those used for the construction of the labyrinth on which are exposed the works of 30 invited artists.

 
At the same time engraved plate and element of the labyrinth, the support of the matrix is constituted by waste wood compressed. The editions, printed in three states of the engraving, reveal the structure of the material employed, in dialogue with the represented subject; a forest of conifers.
