In this work Siekmann sets out to show the effects of the relations of economic power with the public space, gradually becoming an object of interest for private investors and the people on the political scene who are under their influence, so that marginalised groups are often excluded from it. The over two hundred drawings that make up the work are structured along different lines which deal with subjects such as unemployment, town-planning policies, business management and the urban space. The unifying element is the presence of empty pairs of jeans. As if they were an imaginary person going round the city, they are a representation of the excluded: the people without jobs, without papers, without incomes. Without possibilities of consuming, they have created "unknown territories" in the public space.
