I think this a simple and nice experiment I did years ago, it’s a lot of my Tags on a big sheet of paper, a Fabriano 4. It was so simple and effective, I toke some spray cans and maked a mask of my own Tag, using some plastic sheet, and randomly sprayed a background, then the Tags, and finally some more paint and spray paint. Only two colors blue and white, except for some drip of grey. And I know, the photo it’s not one of the best.
I think i have to do some other experiment like this in future, it’s simple but extremely effective hanged on a wall.
