There are also essays by Geza Perneczky, Karol Sauerland, Piotr Rypson, Guy Schraenen, Karla Sachse, Joachim Blank, and Balint Szombathy on the political-cultural-artistic implications of Mail Art. The catalogue contains a transcription of a panel discussion on Mail Art. The participants included Ruth Wolf-Rehfeldt, Klaus Groh, Leonard Frank Duch, Joseph H. Huber, Thomas Schulz, Birger Jesch, Hans-Ruedi Fricker, and Uwe Warnke. The catalogue reprints reviews of the exhibition.
