Greenpeace Australia wants your poster designs.
The challenge: Design a poster that delivers the message "Be a Part of the Action." The message does not necessarily have to be expressed in words, but it should, above all, raise awareness of environmental issues and inspire action.
The rules: Submitted work must be unpublished. Entry is free and open to all, subject to agreeing with terms and conditions (outlined online). Entries should not be signed or have any identification on it – judging will be done through ID numbers. You can submit up to three different entries.
