Atenas Graffiti

It appears on an ugly wall behind the High School in first two photos, then on the concrete wall of a city park in front of the Primary School. It is the only graffiti I’m aware of and wonder if it was a school art class project?

A 4 or 5 shot panorama of wall behind high school that I walk by almost every day. There’s more beyond gate at right, next.
More behind the high school gym to the right of above image. 
The front of the high school however would never have graffiti. 
Wall on big city recreation park in front of primary school, more in next photo.
This park has soccer, basketball, volleyball, skateboard, and more recreation.

Though not all great art, it  too seems too well organized to be vandalism.
Note the skate board ramp is also painted with graffiti above & below.

“People say graffiti is ugly, irresponsible and childish… but that’s only if it’s done properly.”
