Anyway. Some of the ubiquitous images you can find almost everywhere are at last interesting. But that is a matter of opinion too.
WhenI am walking on the streets my eyes are always open for graffiti - and I take often picture. Some of the graffiti seem to have a hidden message, a cryptic memo from an alternative universe maybe. Some are mysterious, some show a bit elegance, others are more on the explosive side.
I like the dynamics of the spray lines, sometime they play with colors, other use various shades of black & grey.
Here are some tidbits of my collection.
Maybe you will enjoy it.
