As a marketing and communication professional, I found the following video interesting. Business cards are an important way to brand your organization, while communicating important contact information. They also serve as a method to win free food when you drop it in a local "fish bowl" at a restaurant. I mean...they have lots of different uses. But all seriousness...business cards are often the impression you leave behind after meeting a new business contact.
What is your card like? Mine has three spot colors (gray, maroon and gold), and is on 130 lb. double thick cover. Its a sturdy card, and stands up really well when handing them out or carrying them in your purse.
If you are interested in design, branding, PR or advertising, the following video might be worth the watch. I thought it was!
