||Prélude et fugue
||2 (prelude, fugue)
||1838 ca. – Paris: Maurice Schlesinger
||RISM 201010302 (description of incomplete autograph, at Robert-Schumann-Haus, Zwickau, with notations inscribed by Schumann later on.)
Published by Schlesinger with Adolf von Henselt's Souvenir de Varsovie, Op.51 and Rhapsodie, Op.4 all with the same plate number.
1838 seems right, as these three works are all mentioned under Nouvelles in Revue et gazette musicale de Paris, volume 5, page 223 (barely readable page), 27 May 1838 (see Revue.)
