I unfortunately don‘t speak or understand Polish so that I tried to translate the text by using G****e. Most of the questions could be answered without problems, only for one I identified the wrong answer as correct.
But the nice owner of this puzzle cache was very helpful and gave me a hint so that I could finally locate the box during a short walk through Katowice this evening. Will leave a FP for the idea behind.
PS: we also have a street named after MGM in Lübeck/Germany :)
