it was painted by banksy

It is as strange as dream.

i like this panting because this painting is paradox

Banksy secretly displayed his painting at the British Museum

However, people didn’t realize the painting was strange even after a few days

After a few days had passed and people still didn’t realize it, he posted about it on social media.
This is what I wanted to tell you .
The museum tried to remove it quickly, but many people had already seen it.
 Anyone could notice something strange if they just looked carefully, but no one realized it for days until Banksy mentioned it.  

Banksy wanted to criticize people who only see art as decoration and don’t really care about it.
