Willys-Knight "70" / El Modelo Setenta - Brochure - 1927-1930

Lot of Willys-Knight advertising catalogs and Otto Gerdtzen machinery. Spain, c. 1925–1930

Exceptional collection of original Spanish advertising catalogs corresponding to the American brand Willys-Knight, accompanied by a rare trade catalog from Otto Gerdtzen, importer and distributor of agricultural machinery with offices in Gijón and Madrid.

The lot constitutes an extraordinary record of automotive and industrial advertising in interwar Spain, notable for the graphical richness of its illustrations, produced in a marked Art Deco style, and for preserving original texts in Spanish intended for the Spanish market.

Among the most notable pieces are:

* “El Modelo Setenta – Willys-Knight Seis,” with color illustration of the Model 70 and the motto “Duración larga y económica”
* “Modelo 70 – El Nuevo Willys-Knight Seis,” dedicated to the new model equipped with the prestigious Knight sliding-vee valve engine
* “Willys-Knight Great Six” and “Gran Seis,” with elegant illustrations of luxury cars from the late 1920s
* Technical brochure “Porqué el Motor Knight es Supremo,” explaining the operation and advantages of the revolutionary Knight Sleeve Valve engine, one of the most advanced mechanical solutions of its time
* Delco-Luz catalog, devoted to autonomous electrical systems for homes, chalets, clubs and agricultural holdings, reflecting the rural electrification process of the era
* Illustrated catalog of Otto Gerdtzen, Spanish distributor of agricultural machinery, showing a “Triunfo” brand straw cutter, with technical description, prices and business addresses in Gijón and Madrid.

All the prints feature careful typographic composition and excellent lithographic quality, with illustrations typical of late 1920s graphic design. They constitute a documentary source of great interest for the study of the introduction of American automobiles in Spain, the evolution of commercial advertising, and agricultural mechanization during the first third of the 20th century.

This type of documentation was conceived for ephemeral use, so the complete preserved copies are today scarce and especially valued by collectors of automobilia, historical advertising, Art Deco graphic design, and the history of Spanish industry.
