US State Seal Armorial Banner, A Unique Heraldic Flag

The armorial banner is based upon the pattern found on the shield, for a coat of arms.  In this case the shield on the official US coat of arms gives rise to this flag: the US State Seal Armorial Banner.  Interestingly there are no stars on the blue canton section.  Also the stripes are vertical and start with white, making them end with white.  Stars are missing because they appear in a cloud above the eagle. 

Although this is not an official flag, with the standard rules of heraldry applied to the shield found within the official US Coat of Arms, this is the consequential flag.
