What do all these imply? Well, my speculation is simple. The portrait of new ruler of Negeri Sembilan will appear on the garden flower state definitive series collection! However, before the new portrait can be used, the new state ruler needs to be installed first! That is the most likely reason why the garden flower state definitive series collection has to be delayed to a later date (November 9, 2009), and the installation of Negeri Sembilan state ruler must take place first (October 26, 2009).
Actually, the original garden flower state definitive issue was released on December 31, 2007. At that time the ruler of Negeri Sembilan was Tuanku Ja'afar Ibni Almarhum. Therefore, the portrait of Tuanku Ja'afar Ibni Almarhum appeared on the Negeri Sembilan state garden flower definitive stamps (see below stamp image). However, his majesty passed away on December 27, 2008. The new ruler of Negeri Sembilan is Tuanku Muhriz Ibni Almarhum. So, the Negeri Sembilan stamps in the garden flower state definitive series collection (will be released on November 9, 2009) are most likely to have the portrait of Tuanku Muhriz Ibni Almarhum while the other stamps in the series collection will remain the same as those original ones. If so, the Negeri Sembilan stamps will be considered as new stamps.
