Stunningly rare and impressive collection of 12 ink AMQS on a single off-white 7.75 x 9.25 sheet bearing a pencil drawing of Gustav Mahler (signed illegibly by the artist), circa early 1930s. Each composer pens from three to six measures; most also add the title, and, in some cases, additional information or sentiments. The composers represented are: Ernst Toch (from Piano Sonata, Op. 47); Paul Hindemith (String Quartet, Op. 32); Heinz Thiessen (unidentified); Max Butting (unidentified); Alexander Jemnitz (Serenade, Op. 24); Kurt Weill (“Alabama Song” from the Threepenny Opera); Alban Berg (Wozzeck; Berg also adds in German: “So that the desire, after some bars of an aria from Wozzeck is taken even more into consideration, since I am not alone in this”); Arnold Schönberg (Jacob’s Ladder, including the sung text); Edmund Meisel (the film score Symphonie einer Großstadt); Ernst Krenek (Jonny spielt auf); Philipp Jarnach (unidentified); and Fidelio Finke (unidentified). A touch of very minor wear at edges, otherwise fine condition. The confluence of factors that contribute to the importance and rarity of this item is truly remarkable. In addition to the sheer number of composers who have signed together, fully half of the signers (Schönberg, Berg, Hindemith, Weill, Krenek, and Toch) can indisputably be regarded as figures of primary importance in the history of twentieth-century music. More incredibly still, these select six have quoted from some of their best-known and most recognizable works. icollector.com
