In any event there's a bit in the article about the sign you see above.
The story goes that the sign painter asked Katz's owner what he wanted on the sign. The owner said, ‘Katz’s Deli. That’s all.’” The sign arrived with those four words on it, and has been in the front window ever since.
Sometimes the mistakes we make, or the mistakes or misinterpretations others make, improve and perfect. As the sign painter's error did for Katz's.
Sometimes it's our job as creative people to see and embrace the wonderful accidents that make work that would otherwise be merely functional, special.
