We are on a tour of photographic archives and the letter N takes us to the National Library of Norway. From their collection (available via their Flickr Commons stream) I have chosen this rather good portrait of Grace Holst. Who was Grace Holst, I can hear you all saying, and what was her relationship with the famed Gustav of the Planet Suit fame? The answer is, I don't really know, and other than the fact that she was a Norwegian-American soprano, I can find no information about her. So, if you are looking for a theme this week, it could be pictures of unknown people. We all have these amongst our collections of family photographs - they may be cousin Ethel, or Uncle Walters' "friend", or they may be a semi-famous Norwegian-American soprano. You don't need to follow that theme suggestions - there are always fur coats, strings of pearls and the inevitable hat. Whatever you follow - or ignore - just post your posts on or around Saturday 10th July and add a link to the list below. And whilst you whistle a happy tune, take a look at what is coming up.
