‘Once Upon a Time..., a look at art in Belgium in the Nineties’, was an exhibition of the collection of contemporary Belgian art which the Cera Foundation was able to put together during 5 years of patronage. - I pulled a bag over my head and tied up my feet and hands. I fell forward and lay on the ground. - Cera Holding is a financial group. The contemporary art collection was predominantly bought by Paul Tanghe, Luk Lambrecht and Bart De Baere, current director of the M_hka. - After half an hour I was untied by Mauro Pawlowski.
