Piano part and complete set of parts. A deep impression with the piano part having both the original blue wrappers reading "Clavier-Werke von W.A. Mozart. [29]tes Heft" as well as the series title page which bears an engraved vignette of a stone monument (with the series title etched in it) surrounded by a waterfall and woodland creatures (a snake and an owl) and reads "Saemmtliche Werke für das Clavier mit und ohne Begleitung von W.A. Mozart, [29] Heft." A catalog for the series is on back of blue wrapper. See MUS-5968, the Piano Quartet, K478, and MUS-5970, the Piano Quartet, K493, both part of this same Haslinger series.
