This book reproduces all of the known 'Neocolor' drawings by the Swiss artist, who died in 2012. Peter Fischli and David Weiss began working together in the 1980s as artist duo Fischli/Weiss, as well as their alter egos Rat and Bear. Before that, parallel to travelling, David Weiss drew all other activities and non-activities with pencil, coloured pencil, ink and Neocolor wax pastels. The 'Neocolor' drawings, for which Weiss used a technique that many will remember from school, form a self-contained group of works from the period between 1977 and 1978. The success of this publication is in conveying the properties of black pages as negative drawings, whose motifs become visible through scratching away to the coloured layers underneath, in an intuitive way. Published on the occasion of the exhibition at Weiss Falk Gallery, Basel, 2021. English and German text.
