After 70 years on the throne, Queen Elizabeth II passed away on Thursday. Upon his mother's death, Charles assumed the name King Charles III. The queen's death triggered a series of long-rehearsed plans, dubbed "Operation London Bridge," to organize what follows the death of an important and enduring figure, an endeavor that is complicated by her having passed in Scotland. Thousands of people are expected to pay their respects to the queen when she is laid to rest in London in the days ahead. The funeral of the queen is expected to draw heads of state and important figures from all over the world.
Many countries use Queen Elizabeth II's name, image and iconography on passports, money, flags and stamps. In the U.K., her portrait covers stamps, bank notes, coins, post boxes, official government signs and more. The task will take a long time and cost a lot.
