Simple But Expensive Artwork

I recently came across this picture online but that is not why I am including it in my blog post, this simple-looking painting was sold for a whopping 3 million dollars (#960000000) that's 960 million naira. I decided to make findings as to why this kind of a painting that my little sister can easily make a clone of with the use of water/postal color would cost that much. I got an answer to my question, the simple reason i costed that much was because it's a painting by a famous artist.
