Issued in 1966, this banknote reflects Colombia's mid-20th century monetary system based on the gold peso standard (Peso Oro). The allegorical winged female figure on the reverse represents the Colombian nation itself, while the mountainous landscape and palm trees symbolize Colombia's geographic diversity and natural wealth. The dual portraits on the obverse—Simon Bolivar and General Francisco de Paula Santander—honor the military and political architects of Colombian independence and the nation's founding republican principles.
The obverse presents two portrait medallions in ornate ovals: on the left, Simon Bolivar depicted in military uniform with high collar, and on the right, General Francisco de Paula Santander in formal dress with bow tie. These are flanked by laurel wreaths and separated by a central ornamental peacock with elaborately rendered spread tail feathers in blue and red. The entire composition is bordered by decorative geometric patterns in blue and pink/red against fine horizontal line work. The reverse features an allegorical winged female figure—personifying Colombia—positioned centrally with an industrial or architectural symbol to her left and an expansive landscape vista to her right including mountains and palm trees. Above this scene sits a circular medallion containing a female profile representing Colombia. Corner shields bearing 'PESO ORO' text complete the decorative scheme. The background throughout employs fine line work in orange and blue tones, characteristic of high-security currency design.
