"Canh Sat Quoc Gia" - National Police Cover Cover to the Vice Commander of the National Police. My Tho 23 March 1972 cancel ties 10-dong stamp to the cover. The military rate for mail sent to military personnel during this period was 25-dong, so this cover appears to be deficient by 15d. Perhaps mail to the National Police was allowed the discount 10-dong rate normally reserved for use mail sent from military personnel. < Back < Imnaha Stamps Home Original content ©2008 Andrew Crenshaw - All Rights Reserved.
