On the 1st of January 2018 COLLATERAL visited the exhibit "Taart in de brievenbus" ("Cake in the mail box") (01.01.2018 – 31.01.2018) in a private house in the Belgian village of Sint-Maria-Horebeke, displaying works and interventions by Celine Aernoudt, Inca Garnica, Sofie Marijnissen, Evelyn Vanoverbeke and Hanna Ravnsborg Hollevoet. In one of the rooms, Hanna Ravnsborg Hollevoet put a notebook inviting the visitors to write down their wants or needs. She promises to give them what they want (in exchange for 10 euros), in the form of a letter. COLLATERAL was in need of a contribution (“een bijdrage”).
