Portraits of a dynasty: North Korea's ever-present Kims

Smiling images of the Kims are everywhere you go. Portraits are mandatory not just in public places like train stations, hospitals, schools and factories, but even in private spaces such as the living rooms of apartments.

Portraits must be hung high, so that no one can stand above the leaders, according to government minders who accompany visiting media and tourists.

As the night falls over Pyongyang, giant portraits on various buildings get lit up.

North Korea remains one of the most tightly controlled societies on earth, with most of the country closed to outsiders, but groups of tourists are allowed to visit Pyongyang and a few other sites, providing the impoverished country with one of its few remaining sources of foreign currency.

For those visitors, another reminder of the all-encompassing influence of the Kim family is the lapel badge, bearing the image of Kim Il Sung and Kim Jong Il, worn by all North Korean citizens.

The badge is presented to every North Korean when he or she turns 12, and from then on they are required to wear it whenever they leave their home. The badges are considered sacred and are not for sale, say government minders.

"We, all North Koreans, always wear the portrait badge like this. The most important part of a human body is the heart, right?" said An Sol Yong, a music teacher at a teacher training college in Pyongyang, during a government organised visit for foreign reporters. All her students wore the badges pinned to their white shirts.

"Being together with our dear leaders through a badge hung on the closest place from our heart means that our belief that we won't be alive if the great leaders had not existed is kept in all our hearts."
