Earth from a Treehouse

This painting is hanging in my room since I found it in a abandoned box at my parents house. My uncle made it before I was born. Story goes that my mum got a new set of colours when her younger brother passed by. I don't recall who asked but at the end he painted it in a relative short amount of time (because he drew the motive many times before) and my mum was a little bit pissed because he did it so fast. He then gifted the picture to her and this is why it's also written on it. My mum wanted to make sure he won't forget it belongs to her.
Now it's mine and reminds me that even my parents and my uncle where young once.
