Centered a bit to left, crayon mark through right column applied by printer, likely due to inconsistent impression, most striking, Fine, Never Hinged (Unitrade CL43Piii; cat. $4,550)
Side margin inscriptions are noticeably weak and the "-PAL-" printed letters on both sides are thinner than those on the issued sheets.
