Fahimah Badrulhisham has kindly created a series of A2 signs with faith and anti-coal messages for ARRCC supporters to hold up at actions, particularly Move Beyond Coal actions.
You can get them printed as A2 board mounted posters at Officeworks. This would work well because the placard can be held by individuals and held up high if you're at the back of the group photo. The ARRCC banner is much larger and needs to be held by two people.
The following links provide the PDF that you can download and offer to Officeworks.
