Posters are the one thing where there is no limit to creativity, as a matter of fact if it is limited than its not a poster, its just a simple piece of paper, if printed, ofcourse it will never reach that phase.
A well designed poster can attract millions of people, regardless of the medium it is being displayed on. The most basic factor that designers consider in mind is, to make the poster/banner stunning as well as to come up with such designs that will interact emotionally with the viewers.
These posters are such examples exhibiting both characteristics. Have a loot at them yourself and decide.
