“When I dip a copper plate in a bath of nitric acid, the acid is my knife. I don’t think of it as an imitation of a hole: for me the hole is real.” (Antoni Tàpies). Video about the exhibition ‘The acid is my knife’ at Museu Tàpies, 2020, and with footage of Antoni Tàpies making prints, from the BBC Omnibus documentary, 1990.
