I got this craft book for kids from a charity shop in Austria earlier this year. Austria doesn’t have the same volume of charity shops as the UK, but when you do find one they’re usually really good, especially in small towns, where vintage isn’t really a big thing.
Amstetten is the most extremely average place in Austria. It’s a largish commuter town in between Linz and Vienna. You have no reason to visit it. Its main claim to fame is that Josef Fritzl lived there. I was there to teach in one of the schools as a visiting teacher.
