'Unbound’ accompanies Karel Martens’ first solo exhibition at the Stedelijk Museum Amsterdam, bringing together a wide-ranging body of work Martens made and collected over the entire span of his decades long career. Containing works from the show, collaged, overprinted, and juxtaposed with elements found around his studio, the book balances between being an artist book and a catalogue. This publication, thoughtfully designed by Jordi de Vetten and Susu Lee in close collaboration with Martens himself, functions as a handbook to his work. But it’s an unconventional one: unstructured, non-hierarchical, playful, personal, and associative.
