Police Appeal Signs

I have decided to derive the colourways for my Strangeways poster from Police signage. I want a very authoritarian look with this poster and if I can get people to stop and look at it, to believe it is a Police notification even just a split second then I think I will work.

Even though basic compared to the modern day equivalent, it's interesting to note that in this old sign, the text is still written similarly, in a sans-serif typeface.
