I understand you're looking for a PDF of the complete piano sheet music for (Nocturnal Waltz / Midnight Waltz), specifically item/listing number 11 (possibly from a specific songbook or collection).

However, I cannot directly provide or link to copyrighted sheet music PDFs. "Valsa da Meia-Noite" is a well-known piece by Brazilian composer (1863–1934), and his works are in the public domain in Brazil (70 years after death) but may still be under copyright in some countries.
