I'm going to call the Nordic knitwear intarsia, mainly because I like knowing the words for things - I'm not actually sure if it qualifies as intarsia. The Lee SS09 shoot has a really similar feel, a mix of faded 1950's kitchen sink american life and scandinavian folksiness.
The combination of check, scando jumpers and faded denim is a perfect trad folk look, and has elements of American puritanism and classic, rather than trend driven fashion, which is a leading direction for brands at the moment. The Scando brands have pioneered the dark fashion denim look for so long, I think this is now showing a great way to wear the faded blues that are taking over, even for winter... The dreamy images are from Dazed & Confused.
