The Fondation Custodia has invited two Dutch artists, Siemen Dijkstra and Anna Metz, to present their work on the art of paper and more particularly on the practice of engraving. Anna Metz is interested in etching and her practice is unorthodox. Her work, intrinsically graphic, changes throughout the engraving process. She deliberately lets the acid bite a metal plate until it breaks. She adds bits of paper, textile and aluminium foil to her dies. She plays with chance, which she stages. The print, with its initial motif of bushes, old clothes or bodies of water and sand, is definitively transformed. Yet even after all these experiments, most of the artist's etchings still (or again) evoke the landscape or still life she had chosen as her subject. In her process, freedom is master. Despite her choice of technique to produce several copies of a drawing, none of her prints, even from the same plate, are made to look alike. As paradoxical as it may be, Anna Metz prints "editions of single copies".
