Thank you S.C. for all your kind words - I am blushing! - I should answer you in a long time - but I did my pleasant work now and looked into your daily photographing of your town. You show Amsterdam as it is. When I go there (I hope) I will see it as I wish. So thank you for remaining of realities!
Grafitti is everywhere. I really like the artistic stuff, but not so sure about just spraying 'tags' on people's walls. It is definitely an artform here to stay forever,
Unwelcome graffiti is a weed.
As the expression goes, graffiti like this is... not my cuppa tea... :-)
