One of the chalenges of that prevention campaign was decorating two different bus, one that go to a travel circuit in my city, and other specific to transport the kids from their school to the Prevention School. We worked with some specialised company in order to best decorate all the bus. We had to redesign all the image in coreldraw to turn it in vectors. Here's the wonderful result, those colorful world gain an extra movement and add more colours to the roads!
