HAP is an artist group founded in 1999 in Ghent, Belgium by Jens De Schutter, Piet Mertens and Wim Waelput. All objects in this artist book were manufactured in the studio of HAP. They are parts of installations, tools or study objects. By conceiving this publication as an auction catalogue, the objects claim the status of autonomous sculptures. With text by Dieter Roelstraete and design by Boy Vereecken and Kasia Korczak.
