Copyright terms are quite complex, summarized here:

http://www.copyright.gov/circs/circ15a.pdf

As best I can tell, the copyright on material published in 1972 lasted 28 
years but automatically renewed for another 67 term, so it's until 2067.

Barring unlikely action by Congress to reinstate sane copyright terms, the 
term of anything published since 1964 is effectively infinite.
