2012 (02) House of Windsor (Stamps) - RM - Buckingham Palace CDS + Doubled 2015 Long To Reign Over Us

Excellent Royal Mail cover........

Full set of the stamps cancelled by the sought after Buckingham Palace CDS, but then the cover has been Doubled with the Purple 1st Class from the Long To Reign Over Us M/S & the Label, cancelled by a Buckingham Palace SW1 H/S...

I doubt anyone else woud have done this, so this is 'probably' unique....
