I still send invoices out on paper, and I still prefer actually licking stamps to the new-fangled self-adhesive kind. And I like to choose stamps by the pictures on them, so I occasionally go to the special philately counter at my local post office. Today I bought 5 Franz Kafkas and 5 Klaus Graf Schenk von Stauffenberg and Helmuth James Graf von Moltke. The man at the counter told me, incidentally, that someone asked for "the Tom Cruise stamp" the other day.
The Kafka stamp is illustrated with a sketch by the author, which seems to show someone in a state of despair at a desk. The writing is vertical, just to make you feel slightly unsure which way round to stick it. I stuck it vertically, which seemed appropriately incorrect.
There's nothing like an official Deutsche Post stamp to show a writer has entered the canon. Over the past few years, they've philatelised Adalbert Stifter, Hermann Hesse, Astrid Lindgren, Joachim Ringelnatz and now also Golo Mann. And the organisation Aktion Patenschaften für verbrannte Bücher has a list of authors whose books were burned by the Nazis, which also tells you which of them have been stampified. It seems Deutsche Post is trying to make amends for Goebbels' crimes by putting as many of these writers on stamps as possible: Brecht, Kafka (twice), Kästner, Kisch, Kolb, Lasker-Schüler, Thomas Mann (twice), Werfel and Zuckmayer.
