Great Britain 1855 1d red brown Plate 25, SG29a

SKU JP5644

Great Britain 1855 1d red brown Plate 25, (Neal's Steam Press Experimental Printing) SG29a.

A very fine and fresh unused imperforate block of four lettered 'GK-HL'. A lovely multiple without any of the usual heavy creasing as normally seen on this failed experimental printing.

Very rare as only a half sheet of imperforate stamps from the different shade of plate 25 exist, with most being in poor condition.

GP Specialised Catalogue No: C8(1)h.

Accompanied with a 1985 Royal Philatelic Society (RPS) Certificate of Authenticity.
