I was in Delft last months (it's very close to Rotterdam, location of the 2024 Eurocon) and you can still buy very similar vases in the city. And right next to the highway, there is a giant version of one of those oddly shaped vases.

I have some Delftware (as well as the similar Frisian Blue, which also was inspired by Chinese porcelain) at home, inherited from my parents. Just small piece, though, nothing like this.
