PERAK 1965 (VARIETY) 5C PAPHIOPEDILUM NIVEUM TRAFFIC LIGHT BLOCK MISSING YELLOW
5c Paphiopedilum Niveum traffic light block x 6 missing yellow. Unique positional piece. Margin virtually separated otherwise and fine. Mint never hinged. SG165b; SC140var; ISC163i
Note: the error affects the androecium at the centre of the flower and the leaves (resulting in them appearing blue rather than green due to the colour being made from a mix of blue and yellow inks)
