I have concluded that what make the advertisement really special and attractive is the creativity and uniqueness of the advert. Usually, what makes it much greater and different from other simple advertisements is that it applies things that are realistic to audience, where they can actually experience the product itself.
Ikea. The advertisers actually placed real furniture to represent Ikea so that people can experience it as though they are sitting in living room with a comfortable sofa and a nice stand lamp.
Coca-cola New Grip Bottle. I definitely find this advertisement very amusing. Who would have thought of actually putting the material that instantly grip on your clothes? Well, Coca-cola advertisement does! It does attract the people at the bus stop to recognize the new product while gripping their clothes when they were leaning on the poster. Hands down, great example of bus shelter advertisement.
