The printed and bound version of the Constitution figures prominently.
"The 1975 Constitution of the People's Republic of China was promulgated by the 4th National People's Congress. The offices of President and Vice-President were officially scrapped under the Constitution.
This Constitution reduced the total number of articles to just thirty, compared to 106 of articles in the 1954 Constitution of the People's Republic of China.
The 1975 Constitution witnessed an integration (in part) of the State Constitution (the PRC Constitution) and the Chinese Communist Party. The Constitution states that the People's Liberation Army, the armed services of the PRC, is to be controlled by the Central Committee of the Communist Party of China and Chairman of the Communist Party of China. Such linkage between party and state would no longer be seen in later Constitutions, particularly after 1982. The most significant link, however, came in Article 2, which stated that the Chinese Communist Party was the leading force of the Chinese people.
The 1975 Constitution remained in effect for about three years, the shortest-lived constitution in the People's Republic of China's history."
