How did the artist put the QR code on the painting? Did he also painted that one out? That interest me a lot since that is not a digital product or a printed one.
Anyways going back to the topic. Most people who are coming to bitcoin are just looking for easy money scheme without even realizing that they can really used their skills and get paid easily by doing such thing. That is why I always do tell the newbies to learn some sort of skills like arts such as this one.
I have here my examples

The QR code can change with slightest error in those white and black blocks and thus can confuse the scanner and may show the invalid QR code. I am pretty sure that the person might have printed the QR code and then stick it their. His art might have been painted already on the wall. Then later on he might have put it over the wall. Because yes that is highly impossible that he will draw it and with those brush strokes it can distort easily.
