It may be acquired at the auction during the quest Open Sesame!, either for 20 or 60 (only if you successfully got information from Yaromir and then told Vivaldi). If you gained the necessary information from Yaromir by correctly answering his question, buying the painting would later start the Avid Collector quest in which the painting can be sold on to Marcus T.K. Hodgson, a famed Novigrad book dealer, who will pay quite a tidy sum for it.
- It's mentioned in the document List of objects in need of restoration found later on in the vault.
- With Blood and Wine expansion, it's possible to keep the painting while still completing the quest by first hanging it in Corvo Bianco, then selling it to Marcus. However, the painting will still be hanging in Corvo Bianco after selling it.
- While you can do this to keep it for your home, there's no way to put it in your stash as it'll always be marked as a quest item.
- If you already sold it and re-added it via the developer console you will not be able to hang it on your wall.
