• Because all pages of this magazine weren't able to be viewed, a copyright renewal search was done for the years 1965 and 1966 for periodical renewals for the Baltimore and Ohio. Nothing from the railroad was located. While it's likely the magazine was never copyrighted, I will license it as copyright not renewed to be certain.
