While it isn’t a perfectly cropped logo, this is still a nice subtle use of the Coca Cola logo to create simple imagery.
'After getting the green light from coca-cola germany division for the use of the smiley, we worked all night to realize the finalized proposal. The next morning printed posters were distributed throughout the city. We did not lose any time because there was a small possibility that the board of directors at coca-cola would have changed their minds in regards to the use of the logo – as this is the first time that coca cola accepted showing only parts of the identity for an official campaign. Therefore, before having the chance to appeal any decision, the campaign was already plastered everywhere, making it too late for them to modify it’. —Bill Biancoli
