This publication does not display a copyright notice and thus under the copyright laws of the United States at the time may thus be public domain. I cannot find a copyright registration or renewal for this work either. Thus, there is a good likelihood that this booklet and its contents are in the public domain.
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.
