In the gallery above, the Post Office targets consumers and commuters using experiential activity and outdoor poster sites at one of the service's busiest times of the year.
Post Office created a 'Christmas Stamp Shop' in Covent Garden and is running out-of-home ads in shopping centres and train stations.
Meanwhile, Coca Cola targets rail and road commuters across a number of poster sites.
The gallery also shows shopping centre ads for Costa Coffee, bringing festive cheer nestled in the sparkle of Christmas decorations.
