Rudolf Sikora is one of the most important conceptual artist in Slovakia. The book is divided into several logical units being dominated by the reproduction of works of authors who are listed chronologically. The harmony of the gallery sometimes are break with texts by curators, which also form the bulkheads in the book. Reproductions are designed individually, and each double-page is made with the same principles. However, none of the facing pages are similarly. The whole book is used two columns layout that varies with nuances. The book cover is a strip with photography that overlaps exactly two lines of text on the case. Overwrap, therefore, gives us a free hand in the creation of another visual book.
