The last photo illustrates my following design, which co-incidently worked well alongside the bus stop poster. This print uses the road warning signs as influence, altering the meaning from water to cigarette butts. It is a simple idea but clearly gets across the message and makes people aware of the issue, although not as tragic (yet!) as the sign makes out. These can simply work as fly-posters around town and would be more impressive as an actual road sign.
