Date
(publication)
Source
Harvard College Class of 1926: Twenty-fifth Anniversary Report, a 1951 book. Copyright asserted but it does not appear to have been renewed, so the book is in the public domain. See list of renewals at [1] ; the renewals do not contain this book.
Author
Unknown, but was sent in by Silverstein himself for publication, so presumably him or a photographer friend.
This work is in the public domain because it was published in the United States between 1929 and 1963, and although there may or may not have been a copyright notice, the copyright was not renewed. For further explanation, see Commons:Hirtle chart and the copyright renewal logs. 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 (70 years p.m.a.), Mainland China (50 years p.m.a., not Hong Kong or Macao), Germany (70 years p.m.a.), Mexico (100 years p.m.a.), Switzerland (70 years p.m.a.), and other countries with individual treaties.
