Pos Malaysia released a set of three stamps on October 26, 2009 to commemorate the installation of Yamtuan of Negeri Sembilan. This issue is important as it signifies the use of Tuanku Muhriz portrait in the next coming issue of state definitive (re-issue of Garden Flower stamps). This is to replace the late Tuanku Jaafar portrait in the state definitive issue for Negeri Sembilan.
