Graffiti || Art?

The first few graffiti art are in San Carlos, Mexico, on old abandoned buildings. 

 

I find this one interesting because of the Roman numerals for the date.

 

I'm sure the train people are not happy about the artwork that appears on many of the cars here in the southwest.  This one is nice and colorful.

 

 

Somewhere in Nevada at a desolate junction in the desert......

 

 

Even poor trees are subject to abuse.  Most of the graffiti I see are artistic, but this is a totally different category.

 

 

 I found this one in an area that had once been a filming area, so I'm not sure if this is actual graffiti, or something for a movie.

 

 

I'm not sure where this was taken.
