This is a rare vintage issue of Shonen King Magazine from Japan. It is issue #38 from 1966. The magazine contains a Batman story (part of the legendary Batmanga series by Jiro Kuwata), as well as horror, spy, and many other manga and stories. The cover features a monster that looks like the Creature from the Black Lagoon. The magazine has yellowing, creasing, staining, and internal binding wear consistent with 50-year-old magazines from Japan.
Please see the detailed photos. I have other interesting vintage items for sale.
