Great Britain 1865 1s green Plate 5 (Watermark emblems) imprimatur, SG101var.

A very fine unused with orginal gum right hand marginal imperforate imprimatur lettered 'BL' shaved at top and showing part sheet inscription.

Lovely example of this scarce "Abnormal" stamp imprimatur that was registered on watermark Emblems paper but only ever issued on Watermark Spray paper.

Very rare stamp from the first approved printing sheet being one of only 22 possible examples, many of which are in institutional collections.

Provenance: Ex. "Verus".

SG Catalogue Value: £5,500.
