American Eagle Auction & Appraisal Company is honored to present an extraordinary offering of historically significant automobile memorabilia from the legendary Cadillac Motor Car Company—an enduring symbol of American innovation, luxury, and engineering excellence.

Founded on August 22, 1902, in Detroit by Henry M. Leland, William Murphy, and Lemuel Bowen, Cadillac emerged from the remnants of the Henry Ford Company and quickly established itself as a pioneering force in precision manufacturing. The marque was named in honor of Antoine de la Mothe Cadillac, the French explorer credited with founding Detroit—cementing a legacy deeply intertwined with the city that would become the heart of the American automotive industry.

This remarkable collection offers a rare and intimate glimpse into Cadillac’s engineering heritage, featuring original factory blueprints, technical drawings, and archival documents spanning decades of production and innovation. Highlights include an original 1920 7-Passenger Sedan factory rendering—an exceptional survivor from the early era of luxury motoring—alongside a comprehensive archive of component and assembly blueprints dating from the 1930s through the 1980s.

Meticulously preserved and rich with historical significance, these materials represent far more than technical documentation—they are the very DNA of Cadillac’s evolution. From the drafting tables of early 20th-century engineers to the refined precision of later decades, each piece tells a story of craftsmanship, ambition, and the relentless pursuit of excellence.

For collectors, historians, and automotive enthusiasts alike, this offering presents a unique opportunity to acquire tangible artifacts from one of America’s most iconic automotive brands—objects that helped shape not only Cadillac’s legacy, but the broader narrative of the American automobile.
