I personally adore how people strive to leave their tiny prints in the world. In the small attempt to show, that they have existed and they were here. One of my favorite parts of the walks is staring at these prints - simple texts or stickers on the walls. The way how people can communicate with each other and the world around through it is fascinating.
That is one of the examples, which I found on the walk. The usual one, however I found it hilarious. The sticker of the creature with horns is covered with the sticker of Jesus.
