A young work by Chopin?? 🎹

[chopinobsessed]

Hi! This is my first time posting on here! In September, I found this album leaf/waltz composition on YouTube that was written in 1824. I was researching abt this composition and read that some time when Chopin was fourteen, he collaborated w/ Countess Izabela Grabowska. It had piano solo and violin & piano works. The album was supposedly destroyed in St. Petersburg. Is this an actual composition?

 Are there any more rare works? Pls let me know!

Anyways, here is the only video link I can find; it's definitely worth watching!
