Super Punch and vis-à-vis the enthrallment and repulsion that the markets are experiencing for tokens—
fungible or
otherwise—we really enjoyed learning about these performative pieces from Nouveau réalisme artist and judo master Yves Klein (*1928 - †1962) called Zone de Sensibilité Picturale Immatérielle, who wanted his patrons to experience the void, offering vacant spaces in exchange for gold. The buyer received a certificate of ownership. Eight such invisible works were sold, some with elaborate rituals including throwing the gold in the Seine and burning the bill-of-sale.
