What makes a good poster?

 What I think would make a good poster would be creativity. Don't be borning and just slap on pictures. Go beyond that. Research the place you would want to go to or you have already been to. Get ideas from the information you have researched on. And take notes on what catches you eye, what makes that place interesting to you, then tie it all up and create your poster. To me i think thats what would make a good poster.
