Stamp of approval for Penny Black letter at auction
A letter addressed to a solicitor in Carlisle was the star lot at an auction in London today, when it exceeded the estimated sale value by nearly £1,500.
What made it special was the six Penny Black stamps attached to it.
The letter was posted in May 1840, just five months after the introduction of Britain's first adhesive stamp.
They may have cost six pennies in 1840, but today those stamps and the envelope and letter they were attached to sold for £3,480.
