Background
"Frank Leslie's Popular Monthly began publishing in 1876. In 1904, it was renamed Leslie's Monthly Magazine, and then Leslie's Magazine in 1905. Later that year (in the middle of volume 60), it was renamed the American Illustrated Magazine, shortening to the American Magazine in 1906. It kept continuous volume numbering throughout its history. The magazine ceased publication in 1956. While no copyright renewals are known for the issues, a number of stories that appeared in the magazine had their copyrights renewed."
