I was reminded of Katharine Hamnett's amazing black and white campaigns today. There are some really good ones
Hamnett's perhaps best known for her slogan protest T-Shirts, which she first made in the early 1980s and were worn and championed by popstars far and wide - that T-shirt in that Wham! video for example...
Here she is meeting Margaret Thatcher, who must have been trying very hard not to look at the blaring words of Hamnett's top.
