ownership...
What is tough about the concept if it isn't yours, don't take it? If you didn't buy it or it wasn't given to you, it is not yours. Not yours to take, keep, give away, sell or insert your own excuse here. The same can be said for art.
That being said, I love these rail cars. DH works with these cars everyday and we are embarking on a art project of our own. He is taking the pictures and I will put a book together. We are not going to sell them but make a coffee table book for ourselves. Is that being a hypocrite? Right now, I don't think so.
Why is it we humans feel the need to be creative in public. I imagine that graffiti has been around a long time. These days, it is almost tolerated, the art part anyway. When DH was going to work last weekend, the police were at a house around the corner who had their fence spray painted sometime during the night. Not art but scary stuff. Claiming territory as their own and warning those around, to go elsewhere.
Our homes belong to us...and the bank and this notion that those who don't even live in this neighborhood are claiming ownership, seems unbelievable. Instead of taking ownership of things that don't belong to you, try taking ownership of things that do.
Take ownership of your own property, your family - maybe even your mouth.
Take ownership of your kids, and take care of what you have already been given. If you have ever been robbed, you know the feeling. When my sister had no money, she sent my father the fishing trophy she won as a little girl for Christmas. He was robbed - they opened all the presents and the trophy was gone.
Is the art the same thing? I really don't know but it is a part of our culture that isn't going away. Who knows, maybe someday they will be great artists and paint on canvas. We can only hope...
