In my own sight reading and reading skills quest, I decided to get any random piano piece by any random composer via IMSLP, and ended up with "Alla Minuetto" by M. M. Anhelli. I wanted to learn more about the composer, and maybe even hear this piece played after playing through it. There is no information whatsoever.
The piece is dated 1893 and is "opus 20".
adding: It definitely says that it's by Anhelli
But when I went back to IMSLP to find the piece, it gave a different composer - Mieczyslaw Ludwik Malcz and then gives an alternate name - MM Anhelli, as a transliteration (which clearly it's not).
If it works - this is the piece on IMSLP
