Auction: 163 - The Philatelic Collectors' Series Sale
Lot: 1867
#C22, 50c Carmine, a lovely quality full wide top margin plate no. 21625 block of six, with an extra-wide sheet selvage, wonderfully fresh and well centered, with strong and intact perforations, o.g., l.h. in the ungummed selvage, the stamps n.h., very fine; full top plate blocks of this value are notoriously rare, not only is this the key item for a collection of full top air mail plate blocks, but in point of fact this is actually one of the rarest twentieth century issues to find as such, as it is believed that fewer than ten full top plate blocks of #C22 have survived.
