Earlier there was the Flash Gordon comic strip,, then the movie serials. Flash has continued to reappear over the years in various types of media. In the 1970s, Avon Books published a series of Flash Gordon print novels, of which this is the sixth. Some modest edge wear, a bit of red dye "bleed" from the page edges on the back cover, a used bookstore stamp and price inside. Otherwise, nice shiny, solid copy.
