SOUTH SUDAN MNH, surcharge overprint, unadopted proof with transparant blue overlay without yet a new value on 1 SSP Birds, showing a pair of Shoe-billed Storks (Balaeniceps rex). Unadopted proof without new surcharge value on blue transparent oval overlay on old face value. Note that because of the rather dark blue background, the direct overprint approach didn't look good, so at the end an indirect overprint with an underlying star-like layer of either silver or gold color as basis of the new surcharged face value was adopted, with only one new face value of 150 SSP in white on a dark blue underlay.
