Text in English and German. This book presents a selection from all Tesar's creative periods and an essay introduces the background to this art and its current positioning, which not least raises theoretical questions about the relationship between pictorial art and architecture. Tesar's drawings are presented as a project that turns a vision of Modernism into reality within a manageable personal sphere. The vision conjures up, as modern creative work is condemned to becoming increasingly specialised, an alternative 'art as a life practice', but -- and this is the present level of perception -- one that can ultimately be realised only in individual art projects.
