This is the art work of the 100 peso bill that was presented to the members of the monetary board of the Central Bank of the Philippines back in 1968. The banknote was issued in 1969 and first printed by the Thomas' De La Rue and Co. LTD. of England.
I saw this on display at the Panublion Museum in Roxas City, Capiz. It gives us an idea of how banknotes are designed before they are finalized for actual printing.
