It has been appointed as the agency of record for the non-league club formed this summer by fans in response to Wimbledon Football Club's successful application to relocate to Milton Keynes.
The agency will be advising the club on a campaign to help raise support for the building of a new football ground in Merton, south London, the traditional home of the club.
Trevor Beattie, the TBWA/ London chairman and creative director, said: "Let me come clean - I'm a Wolves fan. Be that as it may, I don't think I'm alone in becoming increasingly sceptical about just what is happening to the game we love. On behalf of all football supporters everywhere I'd like to ask: 'Can we have our game back please?'"
The agency sponsored the first home league game for the club, which took place against Chipstead at Kingstonian FC on Wednesday night.
