1918-20 1½d KGV Sideface Perf 10 'CARTING - FAR NORTH' printed on Unsurfaced Off-white Card and without gum, an unrecorded card stock which differs significantly from the off-white card used for the succeeding 2d Orange KGV lettercards. This appears to be a previously unrecorded and unlisted paper trial. Some splitting at either end along the fold and some light marginal staining on reverse. A major new find
