#C3a, 24c Carmine rose and blue, Center Inverted, another example of this famous 20th century rarity; being position 93, and from the portion of the unique sheet that yields most of the well centered examples. This stamp has most attractive facial appearance with wide margins and deep, rich colors. It has been expertly regummed over a small filled thin spot and strengthened crease. A wonderful opportunity for the collector or investor to purchase perhaps the most recognizable philatelic rarity in existance. Accompanied by a 1979 Friedl Expert Committee photo certificate. The stamp also bears guarantee handstamps of Cole and Sanabria. (see special color photo and front cover photo)
