The world’s first postage stamp, a Penny Black, is due to go under the hammer at the Sotheby’s auction house in London later this year, where it could fetch up to 6 million pounds ($8.3 million).

The Penny Black, which bears a cameo-esque profile of Queen Victoria, comes with documentation dated 10 April 1840 signed by Robert Wallace, a lawmaker who led a commission to reform the postal service. The example is from the first sheet of stamps ever printed.EFE
