This is a truly unique bank note since the backside, which is a replica of the first Thai bank note, is personally signed by all living former and present Bank of Thailand governors. See if you can match the signatures with their names.

Dr. Snoh Unakul, Nukul Prachuabmoh, Kamchorn Sathirakul, Chavalit Thanachanan, Vijit Supinit, Ruangchai Marakanon, Chaiyawat Wiboonsawat, M.R. Chatumongkol Sonakul and M.R. Pridiyathorn Devakul all signed this commemorative note for me.
