In December 2019, Wittus Witt has issued a German postage stamp featuring famous past magic dealers Rosa & Janos Bartl. The stamp comes as one of many extras with Witt’s latest German publication, the A-B-C der Taschenspieler-Kunst. However, it is directly linked to Birgit Bartl-Engelhardt’s major Bartl biography, which came out – also published by Wittus Witt – just a few months earlier last year.
