For the exhibition El casco de acero / Arte de instalación (The Steel Helmet / Installation Art) at Espacios Unión (an exhibition space which belongs to a bank) in 1998, Wenemoser proposed the project OU Banc(o) (U)nion [(U)nion Ban(k)], a performance carried out by 8 guards dressed in full uniform inside one of the two elevators ferrying viewers to the exhibition space. Each of the guards carried a disposable photographic camera. Every one of the 27 trips they made (the number of possible photographs in a disposable camera is 27) was recorded by the cameras, while the viewers were asked to put ski masks, like those used by bank robbers, on over their faces. The photographs were taken simultaneously, so that at the end they show eight different angles at the same time. >
