Postal Restrictions Around the World

Geography@About.com has an interesting article about postal restrictions around the world. Some make sense in a dictatorial-mindset like no "seditious" literature while others make one's head scratch. Some good examples in general are

Afghanistan - No chess boards (It is an "unislamic" game)
Australia - Goods made in prisons or by prisoners (They do not want to break their monopoly)
France - No rulers or other measurement tools using the English system
Iceland - Toys made with lead (There goes trade with the People's Republic of China)
Israel - Used Beehives (New ones still okay)
United Kingdom - Horror comics (No word yet on graphic novels)
