I posted an example of how bad branding by committee can be. But committees are not alone in their capacity to produce crap.

I used to work for a publishing company many years ago. The owner would bring in graphics done by his nephew for our opinion. They were without exception, attrocious. Of course we lied. But we were careful not to lie so strongly that the owner would actually consider putting his newphew on staff. Forever more we called all bad graphic arts, nephew art.

Looks like more than just a few nephews have been busy making logos for hockey teams:

Oh the humanity!
