Paramedic Chris Porosz would, in his down time in his job in Petersborough, England in the late 1970s and early 80s, take pictures of people he saw on the street.
Over the last few years, he's worked to track down some of his original subjects and stage re-creations of the photos that he took back then. They're pretty fascinating -- I like the unrepentant punker who is recreating his pink mohawk for the modern picture. I suppose that if you have enough hair 40 years later to make an 18-inch high pink mohawk you probably should.
Information about the book in which Porosz collected the old and new snapshots can be found here, at his website.
