1912-24 2 1/2d blue overprinted “CANCELLED” type 24 in mint og lower marginal imperforate control “J 17” block of forty eight, comprising of two horizontal rows taken from the foot of a complete double sheet of 960 stamps (Two panes of 480) with annotations in sheet margin below left hand pane “New plate” and “73 000 impressions taken from this plate” below the right hand pane. This spectacular multiple illustrates perfectly some of the concerns regarding new printing plates produced for this issue, the plate wear is unusually more extreme on the new printing plate than the plate used to print over 73’000 impressions. Minor creasing and folds between impressions as to be expected on multiples of this size nevertheless a remarkable and unique showpiece (SG Spec. N21(1)v)
