Dear Fred, Fuck our art and I'll make it less artistic.

This is open protest against the grey ghost who's name happens to be Fred. I guess the artist is saying "look, we are beautifying these abandoned buildings with some legit art. If you are going to paint grey over any graffiti no matter its artistic value, we are just gonna fight you by throwing up stupid shit everywhere." Maybe this gives nice pieces a longer survival time by creating more work for the gray ghost. Also here we have cassettes and submarines!
