I've been looking for simple, easy to grasp, attractive posters on the topic of peak-oil. At my work place, people do stick a lot of posters and read others' posters. A majority of the population at my work place are pretty smart and reasonably educated. Its often easy to find posters on Global Warming, etc., on people's cubicle walls. However, peak oil is still a topic that most don't "agree to". I've even heard some say "It better not be true!" and laugh.
