The folded sheet is the summary of a series of works on soccer, specifically on one of the two halves of the field on which I have often focused my attention. Halfway across a piece of A4 paper I instinctively drew half the size of a football field. Then by folding the sheet on itself I imprinted the other half of the field, thus completing the geometric symmetry. Doubling is a soccer technical term. In this case, with my exercise, not only doubling, but multiplying, since it is multiple drawings, creating a similar multiplicity. As in the Rorschach tables, the progressive specular design engages my mind and perhaps also that of those who watch it, stimulating the mind to give shaper to a personal concept of the image.
