Great Britain 1840 2d Blue Plate 1, SG5.
A very fine and fresh unused original gum example lettered OF. Horizontal crease along bottom frame line, not visible from face and not detracting from this very desirable and difficult stamp.
The two penny blue was issued contemporary with the penny black and therefore shares the distinction of being one of the world's first two postage stamps. The two penny blue is, however, 10 times rarer than the penny black.
Provenance: Ex Dublin Post Office find.
Accompanied with a 2012 British Philatelic Association (BPA) Certificate of Authenticity.
The SG catalogue price is £38,000.
