Canada 1164d, 1164di

1988 Thirty-eight cent Queen Elizabeth II, an impressive positional block of four plus two printed labels, from a mis-guillotined booklet pane, resulting in two very scarce errors - a single 38c stamp and a label imperforate between and plus a 38c pair also imperforate between. Imprint tab margin at top with usual light adhesion along edge as it was originally attached to booklet cover. A rare item of which very few exist, Very Fine, Never Hinged (Unitrade 1164d, 1164di; catalogue value $3,000+)
