Black Shark

Latitude Zero (Japanese Title: Latitude Zero: Great Military Battle) was a film made in the late sixties by Toho. In typical Toho fashion it does feature the usual assortment of Toho monsters. It also features the Black Shark, a wicked cool submarine. When someone makes a paper model of some thing this cool I have got to build it. You can download yours here.
The photo is from the designers website. I'll be posting mine as I build.
