Littering.. In the city of Toronto they thought of a creative campaign to use the littering itself to tell the story to the public. Combined the typography of the form negative words that reflects upon litterers. The medium itself is used to express the message making it much more impactful and sensible. Even the unconsious mind of a hasty bypasser will interpret the visual information to comprehend the desired message.
These images tell the story in a visual way, but could you think of means it is applied to address to the public even more? Take the usage of the medium to a new, even more impactful level? Maybe involve the public in the campaign? Giving them means to engage into this problem, being able to set an example instead of only undergoing the message that littering is for douchebags?
