PENNY-HALFPENNY GREEN: 1½d green lower-left corner block of 4, the third unit with a 30% Void caused by a Pre-Printing Paper Fold, also with coincident printing irregularities appearing as a 1cm-Wide Darker Band Diagonally Across the Upper Units, Diagonal Green Line across the Third Unit, and Heavier Shading below King's Neck & at Lower-Right, a trifle aged & reinforced behind the paper-folds. A dramatic and technically interesting "freak". Ex Millennium (23/10/2002).
