Great Britain 1958 3d deep lilac (Watermark St. Edwards Crown), SG575c.
A very fine unmounted mint, with full original gum, part perforated booklet pane of six. Small tear and part perforation separation on right hand stamp from attempted separation. Nevertheless a fine example of this extremely rare QEII booklet pane variety.
Previously valued in SG catalogue at £3,800 and now exceptional value for such a philatelic rarity.
