Numerical Symmetry and Remembrance

Every year in recent times there is a special postmark for 'numerical symmetry', ie 8 August 08, 9 September 09, 10 October 10.  And again there will be one for 11-11-11 - though this time with a difference as it will be illustrated with a poppy to mark Remembrance Day:

The three poppy stamps first issued as a strip in 2008 will also be on sale from Post Offices again this year.
