A long, long time ago, I was very interested in graffiti. Last year, I walked around in my home town with my camera, and guess what I stumbled upon: A tag from 1988 that had survived for all those years without getting "cleaned up".
I know perfectly well who's behind the artist name "SPARTA" - he was a good friend of mine then, and he still is - but of course I'm not going to tell :-) I was probably with him when he commited this act of vandalism.
To put things in perspective, the tag probably measures around 5 by 2 centimeters, and we were about 11 years old at the time, so it's all quite innocent :-)
