aaaaaaah, those are so cute! I like the cat, and the little skulls on her belt
We still have Playmobil sets from when my family lived in Germany twice for a year, back in the 70s (my dad was a visiting professor there). I absconded with some of them, which my own boys played with while they were growing up and now my granddaughters play with them. The rest are still at my parents' house and have been enjoyed by many grandchildren. We always called them Klickies.
Playmobil toys are extremely durable. I still have some of mine from the 1970s and 1980s, including one of the very earliest, a police officer from 1975. And Klicky was an early term for Playmobil figures.
Where in Germany did you live BTW?
Meanwhile, the mystery has been resolved and the sender has identified themselves. It's not someone rom here, but from another site I frequent.
