Law firm logos often find themselves in the minor leagues of the branding world.

For all the work that goes into choosing the right font, color and design, they don't generally get much broader public exposure. Beyond websites and office plaques, big firm logos are normally confined to branded pens, umbrellas and maybe the odd stress ball.

But the logos of some firms are now to be found across the world of sport, thanks to some high-profile sponsorship deals.
