I saw this advertisement on a Chinese tribune.The website at the bottom of the image is the resource.
Target audience: the people who work in the office, the students, old people and so on.
It is a advertisement of Mcdonald. It is really creative. It is not only a poster, but also a clock. It is using the sun light, tells people what the time is, and what people can get in Mcdonald.
I will go and buy it right away when I see the advertisement in the street.
