From 26 April 2005 to the end of May 2005, part of a private fountain-pen collection was exhibited in the information area of the Dortmund Museum for Natural History, Münsterstrasse 271 in 44145 Dortmund near the Klinikum Nord. Opening times were Tuesday to Sunday from 10 to 17:00; admission prices were between 75 cents and 3 euros; on Saturdays admission was free on Family Day. On an exhibition area of around 1.80 by 0.70 metres, 36 fountain pens with nearly all filling systems were presented, including transferable, Safety, push, lever, piston and cartridge pens; six fountain pens were exhibited disassembled in order to illustrate the filling technique. Well-known German brands like Geha, Montblanc, Lamy and Pelikan were deliberately omitted in order to give more attention to less known makers like Pichler & Mueller, Moewe, Santis, Transparit, Heiko, Rigoletto or Corrector. The presentation was supplemented by fountain-pen boxes, dip pens with nibs and small ink bottles. In parallel Ursula Stolte showed parts of her collections in encaustic painting and Günter Graban with minerals and gemstones.
