I have been searching for this mural during my stay in the capital of Latvia. It was created by the French artist MTO as part of the Blank Canvas Street Art Festival 2014 and Riga 2014: European Capital Of Culture.
The (very) rough translation would be: I don’t like brick walls so I am just going to tag/write on them.
Sadly, I do not speak French and I cannot trust google translate, so if there is someone who can translate it in a better way, please do so in the comments. 🙂
Have a nice day!
