Nording and Holm are two of the major instigators of the Danish freehand epoch, which still continues to this day. I'm not sure if they get more credit for their excellent pipes, or take blame for all the bad imitations. Johs (Mogen Johansen) does some lovely ones, and others do, but many are not so good, to put it mildly. These pictured make it clear what the original infatuation was.
