You've got to take a look
If you haven't discovered the Swedish National Heritage Board over at Flickr, you ought to take a look. Most of their shots are copies of stuff from a century or century and a half ago of runestones, buildings and such. I haven't found any shots of 19C Viking reenactors yet, but they must be around or coming up: http://www.flickr.com/photos/swedish_heritage_board/
