Stage 7- the first window.
This photo is very deceptive. It appears to be black and white, but it's not at all. it's blue and gray. the only black is on the police call box logo itself. The two white windows are frosted. it was all reverse painted except the logo which was done via other means.
Because it was reverse painted, there is no worry about paint rubbing or flaking off. It's actually on the INSIDE of the window, so handling it is fine.
