hey @lanzjoseg it's a good idea but these some of these locations ,walls are painted over every year or so. A lot of them have been replaced or don't show up anymore on Google but i do mention street locations if that helps.
I will give you one secret of trade, google loves you mentioning them but even better they love unique content, why because that's the name of the game content - knowledge. Although pictures of scenery, flowers and birds are nice, But Art is different, it's priceless, Google sees value in it now and in the future and so much is not even catalogued destined to be lost.
And my opinion (if you read my post about it) you would know ... be well buddy :)
