Two Vintage Expired Cold War Era USA Passports/Travel Document Issued 1966, 1975 For Sale

These are two beautiful Cold War era USA Green Passports in good condition.The passport issued in 1966 prohibits the holder from traveling to communist parts of China as the US did not have diplomatic relations with the Peoples Republic of China in the 1960s (that came later in the 1970s after Nixon’s visit to China in 1972).
The passport issued in 1975 no longer lists China as a country needing special permission to travel to as diplomatic relations between the US and China improved.
It also still lists North Vietnam as a country (as it had not yet formally united with South Vietnam). Formal unification of North and South Vietnam occurred in 1976.Own a beautiful piece of Cold War history with these passports!!
