Im favoring these particular posters at the moment, may tweak it a little more. Images show front and back - the back pattern will be designed to compliment and match the front of the poster.
Apart of the Which? campaign is a symbolic video, here I have taken the step image, created for the other publication and add some animation. Still isn't completely finished but slowly getting there.
Below are some poster ideas, still working on these. The idea is to create a symbolic and image supported idea that Which? is with its customers every step.
