The Irish National Archives has an outstanding collection of photographs, and their images have no known copyright. An Irish tour company has taken a creative approach by combining old pictures of Cork from the Archives with new photographs of the same scene. A description from the tour company's website: Fashion and architecture, modes of transport and advertising, all have changed drastically over the past century and a half. But perhaps most fascinating are the details which have not changed; the buildings, businesses and landmarks which Corkonians walk past every day, and the little human touches which make Ireland what it was then and what it is now. Take a look at the old-and-new photos of Cork here: http://www.myirelandtour.com/ireland-then-and-now/cork.php.
