Private activities
I. Experienced stamp collector, participation at several stamp
exhibitions with awards
a) Posthornserie on letters
b) The development of the German postage after both world wars
c) The element nitrogen in the philatelic world (posters only)
I am always interested in finding serious stamp collectors for exchanging.
I can offer Germany and other Western European countries. My main
interest is in receiving stamps on letters, postcards, stationary,
also mint stamps.
II. Guiding botanical tours for amateurs, particularly in
the vicinity of Cologne upon request
