Public domain. This work was originally published before 1964 and had to have the copyright renewed sometime in the 28th year. If the copyright was not renewed the work is in the public domain. Online searches of the U.S. Copyright Office's Copyright Records web site for "Michiganensian" and "Ensian" revealed no renewal entry for the 1956 Michiganensian. Similar searches of the Stanford University Copyright Renewal Database reveals no copyright renewals for any volume of "Michiganensian" or "Ensian" during the period from 1923-1963. Accordingly, it appears the 1956 Michiganensian either was never copyrighted or the copyright was not renewed and therefore it is in the public domain according to either criteria.
Note that it may still be copyrighted in jurisdictions that do not apply the rule of the shorter term for US works (depending on the date of the author's death), such as Canada (50 p.m.a.), Mainland China (50 p.m.a., not Hong Kong or Macao), Germany (70 p.m.a.), Mexico (100 p.m.a.), Switzerland (70 p.m.a.), and other countries with individual treaties.
