Nadia Kaabi-Linke is researching and collecting traces of the daily urban life, she analyzes them and transforms them finally into art. The book concept is based on this idea by using the analog technique of stamps and seals. The book title »Sealed Time« is placed around the edge of the book, it works like a bracket or seal. Combined with kraft paper, the book reminds of a document of a state authority and visualizes the historical-political aspect of the artist’s work. Published by Kerber.
