THE UNIQUE ONE CENT GREEN
VERTICAL PAIR IMPERFORATE BETWEEN AND AT TOP
unmounted mint 1c Green, vertical pair imperforate between and at top (424e), contained within top right corner margin block of nine (top right vertical pair the error), caused by foldover which resulted in one error pair and some 'wild' vertical perforations (one row of which would have perforated the error pair had it not been for the foldover), exceptionally fresh, bright and crisp, as to be expected the foldover results in a couple of light creases in the error pair, brilliant original gum which is never hinged,
