1975 - « في Château Malou، Truc-Troc كأول مرة عالميًا »

Press clipping from 1975 by Claude Muyls: "Au Château Malou - Le Truc-Troc - En première mondiale". The article presents the operation launched by the artwork lending gallery and stresses how unprecedented it was.

It describes the principle: any visitor could become the owner of a work by offering the artist an object or a service, money being excluded from every transaction.
