The design for the 5.00 denomination is a palmshaped book, symbolizing the protection of creation and invention. The design for the 15.00 denomination is a fusion of the human brain and computer disk. They are locked to symbolize the fact that the respect for the protection of intellectual property rights has been a global goal.
