Hampton Court Palace is one of the best-known and grandest of Britain's historic Royal Residences and is the third in a series of Royal Mail issues featuring Royal Palaces following Buckingham Palace (2014) and Windsor Castle (2017).
The Retail Stamp Book features two 1st Class commemoratives depicting the Great Hall and the King's Great Bedchamber, flanking four Machin 1st class NVI Definitives. The six stamps in the booklet are self-adhesive and printed in gravure as opposed to the main issue stamps which are litho and gummed.
The pair each carries a single stamp with an appropriate handstamp and image together with a cachet confirming the printer and process.
