The sustainability of Ready-mades

Paving the path towards reusing/re-purposing/up-cycling and sustainability, Ready-mades have been inflaming brains, vigorously shacking foundations, and vexing the prudes since 1912, thank to Marcel Duchamp. Considering the very long list of artists that have been taking this route, it seems that this trip is priceless.
