Crop of page 183 of the 1961 Pitt student yearbook, the Owl. This work was originally published before 1964 had to have the copyright renewed sometime in the 28th year. If the copyright was not renewed the work is in the public domain. Renewals for copyrights from 1951 onward (and some, but not all, renewals for 1950 copyrights), as well as original registrations from 1978 onward are available online from the Copyright Office's Copyright Records web site.

Originally this issue of The Owl was published with a copyright notice of 1961, and therefore this issue of The Owl student yearbook would have had to be renewed in 1988. Online searches, regardless of year, of Copyright Office's Copyright Records web site for The Owl, editor Heinrich Bonstedt, the business manager Francis Ronald Miller, or the University of Pittsburgh revealed no renewal entries.
