Cardiff-based agency S3 Advertising has been asking the public to take part in their heart-warming campaign in the run-up to Christmas.
The campaign, S3’s Big Secret Santa, has been requesting for the public to send in their Christmas wishes using the hashtag #S3BigSecretSanta, with the promise that one will be granted on the 17th December.
Instead of simply emailing the winner, S3 will be revealing them for the entire city to see, on JCDecaux’s most seen billboard in Cardiff (backlight 96-sheet, Newport Rd). 
The campaign has already generated a tremendous amount of publicity around the area, including the support of local sport clubs and charities, and has already received hundreds of Christmas wishes.
Three wishes have now been randomly selected and it’s up to the public to choose their favourite from these touching stories.
Matt Jones, CEO of S3 Advertising, said: “We feel we should be giving back to the community, however, we have to make it fair to everybody. The idea of this promotion was to have the people of South Wales making nominations for either themselves or their loved ones, and the public would vote for the winner.
“When I found out who those final three nominations were I couldn’t be more pleased, they’re all really worthy winners.”
Voting closes at midnight on Tuesday the 15th December and the winner will be announced and showcased on the billboard on December 17th.
