When future historians write about this period of history, they may well distinguish between Before Peak Oil (BPO) and After Peak Oil (APO). The graph showing the course of BPO over the years and APO has been taken apart and appears at first glance to resemble a kind of landscape. However, if we look more closely with the help of 3D glasses some of the countries which have already reached Peak Oil, and those that haven't, will stand out. The toy oil barrel exaggerates this and also implies power games.
