1973 (09) Parliamentary Conference - PO - Balmoral Castle CDS

Stonking PO cover with the full set cancelled by the extremely rare Balmoral Castle CDS.

This is the scarcest of all the Royalty CDS possibilities and can only be used when a member of the Royal Family is in residence on the day of issue...

Cat £150 as such... very scarce indeed !
