SOUTH SUDAN MNH, overprint SHIFTED pair of one up and one down of black face value 250 SSP on the star shaped underlay in gold on 1 SSP Birds, showing a pair of Shoe-billed Storks (Balaeniceps rex). Because of the rather dark blue background, the direct overprint approach like for the 1 SSP National Flag 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. The black face values were printed separately on top.
