7th May 1840 - Mulready

Along with the Penny Black and the Tuppenny Blue, several versions of the "Mulready" were made available to the postal patrons of the General Post Office in Great Britain They comprised letter sheets and wrappers in 1d and 2d rates.
This example, used on the second day of official use, is a 1d [Black] folded letter sheet concerning a legal matter.

The cancellation of a 'Maltese Cross' was to be applied to the figure of Britannia, per the GPO directives. As usual, the sending office stamped the back of the envelope with its dispatch mark. As there are no other transit markings, the presumption is that it was posted and delivered in Malton, Yorkshire.

This cover is listed in Mike Jackson's "May Dates" book from the GBPS.
