Andy Murray’s new logo is meant to include ‘heraldic cues’ and ‘capture his energy and spirit whilst subtly referencing his affinity with the number 77’, but it just looks like a few black lines on a white background. Can you do any better?

Andy Murray won Wimbledon on the seventh day of the seventh month, 77 years after the last British man had picked up the trophy – so, obviously enough, he has celebrated that feat with a new logo that combines the number 77 and his initials. The idea that a tennis player requires his own “branding identity” is a peculiarly modern one, but if Roger Federer can get away with it, why can’t Murray.

The logo is fine, but it’s a bit plain. Dan Calderwood of Aesop Agency, the company that produced the design, says it is a “modern mark that captures Andy’s energy and spirit whilst subtly referencing his affinity with the number ‘77’. It’s simple and striking, with heraldic cues that echo his dominance on the court.”

What a load of nonsense. It’s just three black lines on a page. Can you do better? Murray had a fairly disappointing year in 2014 so he needs a more rousing image to spur him on at the Australian Open.
