Monograph documenting an installation by Paul Thek at the Lembruck Museum in Duisberg in the winter of 1973/74. An exhibition catalogue was never published but extensive installation photos were taken, and presented here for the first time. Texts by Michael Krajewski, Marietta Franke, Siegfried Salzmann, Barbara Catoir, and Franz Deckwitz. Includes a list of works in the collection. "This publication is devoted to a little-known temporary artwork: in the winter of 1973/74 Paul Thek was a guest of the LehmbruckMuseum in Duisburg. His expansive environment "Ark, Pyramid - Christmas" ("The Manger") filled a whole room. It was the further development of his installation realized at Documenta 5 in Kassel (1972). This exhibition, organized by the director of the museum at the time, Siegfried Salzmann (1985-1993), was the fourth in Thek's series of atmospheric, large-scale projects in Europe, which engaged with individualized religious symbols. The festive period provided Thek with the occasion to present, for the first time, a self-written theatre piece in the form of a nativity play featuring children from Duisburg. A great quantity of original material and documents have been discovered in the museum's repository and enable a reconstruction of the exhibition in this book, accompanied by an interview that Marietta Franke conducted with Franz Deckwitz, who helped with the installation in 1973." -- publisher's statement.
