A work by Merz 20 years after  his death This year marks the 20th anniversary of the death of Mario Merz (Milan 1925-2003), great protagonist with his wife Marisa of Arte Povera. We remember it with “Che fare?” (1968), an iconic and eloquent work from the De Fornaris collection, requested on loan by most important  museums and kept at GAM, the Modern and Contemporary  Art  Gallery of  Turin.
