CANADA 1930-31 1c green (UNUSED), SG289daCanada King George V 1930 31 1c green, die II, horizontal pair from left of sheet, ERROR IMPERFORATE, SG289da. Brilliant mint quality pair with original gum. The right stamp with a trivial gum wrinkle, mentioned purely for accuracy as one of the finest quality examples in existence. Extremely rare as only 50 pairs existed, and this example is of very fine appearance and especially desirable as a positional multiple. The Stanley Gibbons catalogue value
