- There are no copyright markings on the front or back of the brochure, but because I am not able to examine the complete mid-section of it, a copyright search for any possible renewals was done.
- Copyright renewals for books, pamphlets and periodicals for the years 1961 and 1962 were done, with the focus being on anything from the Chicago, Burlington and Quincy Railroad.
- The above mentioned searches turned up no renewals of any type for the railroad. While I believe the brochure was never copyrighted, I have chosen to license it as PD-not renewed to be certain.
