This is a Vintage Early 1970s Cosom Flying Saucer - Red, Blank, Spiral pattern. This is a very slightly used disc in very good condition. The Cosom Flying Saucer is truly a minimalist disc with classic early lines. It has a spiral pattern on the upper flight plate, and a simple raised lettering "Made In USA" on the underside. It is a mold 4. Look for my listing of the same disc in yellow and blue to round out your set. Thanks for looking!
