With the closure of the post office this cover has become even more collectable.
Full set of Royal Mail 2001 Christmas stamps and special Bletchley Park first day of issue cancel. Very attractive seasonal design hand painted by Graham Tomkins.
The design shows Britain's 'secret' little Post Office at the side of 'Station X'.
This is the seventh Christmas cover from Bletchley Park Post Office. Together they could make a valuable collection on their own.
Grab them while you can.
