The poster is showing a map of our world made out of colourful footsteps. We (as a race) went and conquered the world. Now we are in each corner of it. The way we did it, changed the way we how see it, feel it, taste it..How we speak, how we behave and what we believe, and what we believe is beautiful. But it does not matter where we are, or what cultural differences we have - we should never forget, that we come all from the same place, and are descedants of the same people.
