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

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

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

The lot constitutes an extraordinary testimony of automobile and industrial advertising in interwar Spain, notable for the rich graphics of its illustrations, executed in a marked Art Deco style, and for preserving original texts in Spanish intended for the Spanish market.

Among the featured pieces are:

* “El Modelo Setenta – Willys-Knight Seis,” with a color illustration of the Model 70 and the slogan “Duración larga y económica”.
* “Modelo 70 – El Nuevo Willys-Knight Seis,” dedicated to the new model equipped with the prestigious Knight sleeve-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 sleeve-valve engine (Knight Sleeve Valve), one of the most advanced mechanical solutions of its time.
* Delco-Luz catalog, devoted to autonomous electrical systems for homes, chalets, clubs and agricultural estates, reflecting the rural electrification process of the era.
* Illustrated catalog of Otto Gerdtzen, Spanish distributor of agricultural machinery, showing a straw cutter branded “Triunfo,” with technical description, prices and business addresses in Gijón and Madrid.

All prints feature a careful typographic composition and excellent lithographic quality, with illustrations characteristic of graphic design from the late twenties. They constitute a source of significant documentary interest for the study of the introduction of the American automobile 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 copies preserved intact are today scarce and especially valued by collectors of automobilia, historical advertising, Art Deco graphic design and the history of Spanish industry.
