Talk about putting a stamp on things! Not only is six-time Wimbledon winner Roger Federer ranked number one heading into the U.S. Open today, but the tennis champ is also a pro at creating and marketing a brand.

The Swiss tennis star first came up with a monogram as a form of personal branding, linking it to his signature scrawl on the "Roger Federer" cologne, reports The New York Times. The logo has since evolved into the gold block face statement that Federer created with Nike for Wimbledon (above).

This new, extra-large insignia uses a font similar to those used by famous fashion brands, including Vogue, Louis Vuitton and Giorgio Armani, reports the newspaper. (Could Anna Wintour, an avid Federer fan, be rubbing off on him?)

Now the crest is prominently displayed everywhere -- warm-up jackets, sneakers, even the plastic bags covering his tennis racquets!

Federer admits that he may have "overdone it" with the gold logo at Wimbledon. But, do you think it's okay for tennis clothing and gear to scream the player's signature? Or should the understated and classic tennis outfits of old make a comeback? Let us know in a comment below.
