1975年 - 「シャトー・マロウで、世界初のTruc-Troc」

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.
