A charming relic of Vienna's golden operetta era, this fold-open "Liederkarte" (song card) No. 16 captures the playful romance of the Singspiel Hannerl — the second part of the beloved Dreimäderlhaus series built around Franz Schubert's melodies — with a vivid lithographed illustration of characters Hannerl (portrayed by Frl. Rainer) and Hans (Herr Jari) in period costume, she in a tiered white-and-blue ruffled gown with rose accents, he in a grey tailcoat and golden waistcoat, arm in arm in theatrical pose. Inside unfolds the full vocal score of the duet "Ich weiß nur das Eine" (I Know Only One Thing), with tempo markings including Lebhaft bewegt, Etwas langsamer, and Mäßig bewegt (gefühlvoll), lyrics by Dr. A. M. Willner and Heinz Reichert, music adapted from Schubert and arranged for the stage by Carl Lafite — a miniature piece of Viennese musical theater history you could mail to a friend for the price of a postage stamp.
