Great orginal RR brochure. The color of the engine is just eye popping. The product is a vintage speed brochure from 1946 promoting the Robert Roof Blue Streak V8 Ford race car. The brochure showcases the blue color theme of the automobile, highlighting the Ford make and the United States country of origin. This collectible item would be a valuable addition to any automobile advertising or vintage sports memorabilia collection, especially for fans of classic Ford vehicles and American racing history.
