Once upon a time, there was a man named Peter Ludwig who really liked art. He wanted to collect lots of beautiful paintings and sculptures so he could look at them whenever he wanted. He decided to call his collection the "Berlinka" because he lived in a city called Berlin.
Peter Ludwig collected all kinds of art from lots of different artists. Some of them painted pretty pictures of flowers and landscapes, while others made sculptures of people and animals. He even collected art from faraway places like Japan and China!
People liked Peter's art collection so much that he decided to share it with everyone. He built a special museum called the "Berlinka Collection" where anyone could come and see all his beautiful art. The museum was really big and had lots of paintings and sculptures for people to look at.
Even after Peter Ludwig passed away, the Berlinka Collection continued to be very important. People visited the museum from all over the world to see the beautiful art and learn about different artists. And that's how the Berlinka became a famous and special art collection.
