The exhibition "Blow Up" is a sample of 25 drawings and engravings (each of these serials) collected in a box that the viewer can touch. These engravings show some white men carrying a series of fluorescent tubes.
The image at least is disturbing and should be so because the final work, that is, the place where these sculptures were actually exposed was in one of the most important parks in Brussels.
On that occasion, these white walkers were changing position and place every day so that the viewer will always contemplate a new work. Thus, the work was narrated as the sculptures changed location.
