Lot 18: Philatelic: G.B. 1840 One Penny Black:

LB-MJ, Plate 3, the incredible block of eighteen, intense color and sharp impressions on bright paper, mostly with margins but touched in places and some creasing, neat red Maltese Cross cancellations, overall in a very fine state of conservation for what has been long recorded as the largest used multiple of the Penny Black in existence; one of the most important classic multiples in philately and an astounding exhibition item; ex-Seymour (from which LK/MK were one time cut in order to make the block free of repairs) and Pichai.
