Impossible figures in advertising

Advertising agency McCann-Ericson designed these advertising prints in 2003 and represented them at the Cannes Lions 2003. The producer of Powerade is Coca-Cola. The images are distinguished from others by calligraphy and imitation of drawing on old paper. The prints are based on Escher's artworks "Waterfall", "Ascenging and Descending" and "Relativity".
