1859 10 Gr., indigo (indaco), top sheet marginal block of fifty, with three large even margins and a close but clear margin at foot. Largely unused without gum, the gum having dried out. Central vertical fold between the stamps, position 9 with a small surface scrape. Positions 9, 11 and 21 showing retouches. Fine colour and exceptional freshness.

An extraordinary exhibition multiple of outstanding rarity and importance. One of the largest surviving multiples of the 10 Grana value, further distinguished by the presence of three recorded retouched positions. Despite minor faults, it remains a spectacular showpiece of the highest philatelic significance.
