Sometimes, people feel embarrassing when they order tap water in restaurants. In fact, tap water is not only cheaper, but also, healthier and earth friendly.
Why do people have such wrong value on tap water and think that bottled water is better ? I guess it is because of the power of advertisement on bottled and branded water.
I found that most of the bottled water advertisements in the early last century are illustrative or hand draw. So I came up with an idea that it could be interesting to make a hand draw poster to promote tap water — using old French posters as my inspiration to promote the modern values.
