The Swine World National Magazine May 1917 Vol 4 #10.
It looks like there were some metal clips that went through the spine of the magazine for hanging or storage. There are stains from the metal clips on the center pages.
The top staple is gone. There are no missing pages. No writing or markings in the magazine. Some yellowing of the pages. Stains and wear consistent with a magazine from 1917. Some small tears on both the front and back covers. See photos.
