The purpose of sign is to inform us. We use many signs each day to guide our lives:

• Street signs
  
• Traffic signs
  
• Advertising
  
• Caution signs
  

The sign I have posted is supposed to be advertising but, it does not tell the reader anything because it doesn’t say what merchandise is in stock. Watch for signs around you over next week, see how many signs you find that really have no informational value!
