Lot 60161 – 1851, 3kr black on yellow, an extraordinary example with huge margins

1851, 3kr black on yellow, an extraordinary example from the upper left corner of the sheet, showing exceptional margins on all sides enabling portions of three neighbouring stamps to be displayed, cleanly tied to piece by “148” numeral of concentric rings from Villingen, certainly one of the finest examples known; signed Brettl BPP.
