Lot 61548 – 1843, 30r black, worn impression, semi-xiphopagus with « filigrana de sutura »

1843, 30r black, worn impression, featuring the elusive « filigrana de sutura » (« suture » or « stitch » watermark), graced by excellent margins with outer frame line and complete interpanneau dividing line at base, used with Bahia cds, faint thin spot of no importance for this item, combining the rarity of this « watermark » and the semi-xiphopagus feature, stated to be an « extremely rare piece, maybe unique » by the renowned expert Peter Meyer in his 2014 certificate.

Note: The « suture » watermark is caused by the splicing of the felt that carried the wet paper, during the process of its manufacture, which was made with metallic threads. It is an accidental filigree with the appearance of a suture, when the stamp is examined in benzine.
