Lot 40303 – 1878, 1,000r grey slate, the finest block of ten used

1878, 1,000r grey slate, the phenomenal horizontal block of ten from the right of the sheet, exhibiting the ABN “American Bank Note…” marginal imprint within the area of the lower right stamp, decoratively cancelled with each stamp showing a strike, uncommonly neat applied, of the “Rio de Janeiro/23 Jan 84/(3. T.)” cds; the vastly superior quality example of only four blocks of ten recorded, being the second largest 1,000r multiple known.

Provenance: Alemany Indarte and Dr. de Amaral Machado.
