Graffiti by Stencilling

Just when I thought the City of Tainan wasn't doing anything about graffiti, I saw 2 guys painting over some graffiti that I had snapped earlier.

Then I realized that it wasn't the city of Tainan cleaning the wall, it was the owner who was developing the empty lot behind the wall, he was looking for businesses to locate there.

One form of graffiti that I see is 'graffiti by stencil', the art is probably cut in cardboard and then taped to the walk and spray painted. Here are some examples, I never get the point, I guess it's art for art's sake.

I think this Chen Shui Bian, the past president of Taiwan who is now on trial for taking bribes.

This one is nice in one color.

I suppose with two colors it requires two stencils.
