Selected study unit - Petroleum Philatelic Society International
February 12, 2012
Although the use of petroleum can be traced back to asphalt in the construction of the walls and towers of Babylon, the rise in petroleum's importance is closely linked with the development of the internal combustion engine. The Petroleum Philatelic Society International studies the depiction of the petroleum industry on worldwide stamps, examining its origins, exploration, production, transportation, usage and associated problems. Hover your mouse over the stamps shown here for more information about the topic as depicted on the stamps, then join PPSI to get the quarterly Petro-Philatelist to learn more about the industry and its appearance on stamps.
