If an agency was contracted to make the Stop sign... (video)
I first came across this video on Mike Kujawski's government communications blog. It's an awesome little video made by AdFreak which shows the consulting process that a firm might have to go through if they were commissioned to develop the Stop sign today.
Having worked for a consulting firm and in marketing departments, I love this. I think I might have actually had these clients before. :)
