Many 90° rotated label holder schemes are executed without the good space-saving results shown here. And while rotated labels can add to visual clutter, when all labels have the same orientation the effect is less noticeable. Labels here, however, are slightly larger than the metal plate holder eventually causing unkempt look as they age.  *****
