The words bưu chính on all the stamps mean postal, this also denotes that the stamp is after the reunification. A few close ups after the jump.
Propaganda art in Vietnam was very much influenced by Russia and China in the 50′s and 60′s. These stamps portray a more developed propaganda style unique to Vietnam.
