"The White Skulls"

 "A gang of mysterious ex-Nazis who dress in tight fitting costumes of black, painted with the white ribs of skeletons. On their black hoods are painted ghastly white skulls. They control a strange and amazing power to control the shape of matter; they inhabit a hidden domed underground city, far beneath New York City. And it will take all the cunning and power of The Shadow to defeat their sinister evil!" -  J. Olsen
