1895-96 QV 3r brown & green OVERPRINT DOUBLE, ONE ALBINO (SG 20lC). Superb fresh M example, the albino impression above the inked overprint with strong offset on reverse, also with TALL SECOND "Z". This is the DISCOVERY COPY for the SG listing in 2002 and, although a pane of 12 may have originally existed, this remains the still apparently unique example recorded. An exhibition showpiece for connoisseur. Photo-cert: BPA. Ex Griffith-Jones. (cv£2400, see SG footnote re variety C). See additional image and of certificate.
