1857 DIE 2 1D PLATE 48 WHITE PAPER ERROR IMPERFORATE (SG 38a Spec. C10l). A good unused example from 1857 Die 2 1d plate 48 ERROR IMPERFORATE with four neat margins in a nice pale shade lettered GA (SG38a Spec.C10l). RPS Cert. states "horizontal crease at top, cleaned of soiling and re-gummed - is genuine". Faults but rare. (Ref 63679).
