1852, William III. 1 silbergros reddish-orange in block of 4, nice fresh and deep colour and good to large margins, neatly cancelled by circle of 9 bars of Luxemburg. A tiny thin between the two right-hand stamps, slightly affecting the top line of the lower right stamp only and the same stamp tiny marginal tear at right, just into the outer frameline but merely touching the design. Blocks of this stamp are extremely rare, this one being one of the finest in terms of quality. Certificate Demuth BPP (1985)
