World Leader Trading Cards

I read once that 25% of American grade school students couldn't identify the current U.S. president! Here's a chance for kids to learn their world leaders. The front of the card would be a colour photo the leader, with the country and his or her official title. The back could contain a small map of the world, with the country lead in solid colour or outlined. Stats should include dates of election/appointment etc, size of country, type of government, up for re-election date, and other pertinent information. Smaller countries would be printed in smaller quantities, hence increasing their collectability, with limits on the really huge ones... "China AGAIN?!?"...
