BEST LOGO: FedEx

The fedex logo is considered as one of the best over the world and for a reason i had to take some time to believe it

the reason is: there's an arrow in the logo that isn't visible to the ordinary user

The arrow was indeed intentional as a secondary design element,” says Federal Express Corp. spokesman Jess Bunn. “If the viewer sees it, it's a neat, interesting visual bonus. If the viewer doesn't see it, that's OK. It's still a powerful logo.

why i had to take some time to believe it????

because i didn't noticed the arrow from the first time, and what they always said about the visibilty of the logo isn't the case here

the designer won prizes for this, but i believe fedex worth to win prizes too

why?

because they gave the designer the space to CREATE not to do a logo, and they support him in this

I wish i could meet such clients :)
