1885-97 2a6p yellow-green, type 2 opt with long Hindi, upper marginal block of 6 (3x2) with part centre guide, showing error 'GWALICR' on centre stamp in upper row, brilliant o.g. R1/5, May 1896 printing. One of 19 examples recorded by us (out of a possible 26), and arguably the finest extant positional se-tenant multiple, the only other multiple of this size being the corner strip of 6 ex Ulrich. A superb and desirable piece. (Image)
