North Korean leader Kim Jong Un's daughter will be featured on stamps to be issued by the country's authorities on Friday, according to the website of state-run Korea Stamp Corp., in a move that raises the profile of Kim's potential successor.

Kim's "beloved daughter," believed to be his second child Kim Ju Ae, who is around 10 years old, will appear in five of the eight stamps to be sold in commemoration of the successful test launch of the new "Hwasong-17" intercontinental ballistic missile last November, the website showed.

The stamps are based on images released by North Korean media, and carry descriptions that say the photographs were taken on Nov. 18, when the ICBM was fired, and Nov. 26, when the leader and his daughter took part in a photo session with people who contributed to the missile's development.

The girl accompanied Kim at a military parade held on Feb. 8 in Pyongyang to mark the 75th anniversary of the founding of the country's armed forces, according to pictures released by state media, reinforcing speculation that she is being groomed as a potential successor.

She has been described as "most beloved" and "precious" by state-run media. Kim is believed to have three children -- a son who was born in 2010, Kim Ju Ae born in 2013 and a third born in 2017 -- according to South Korean media.
