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

Lot of Willys-Knight advertising catalogs and Otto Gerdtzen machinery catalogs. 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 to automotive 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 Castilian aimed at the Spanish market.

Among the standout pieces are:

* “The Model Seventy – Willys-Knight Six,” with a color illustration of the Model 70 and the motto “Long-lasting and economical.”
* “Model 70 – The New Willys-Knight Six,” 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 pamphlet “Why the Knight Engine Is Supreme,” 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, dedicated 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 straw cutter brand “Triunfo,” with technical description, prices and commercial addresses in Gijón and Madrid.

All the prints feature careful typographic composition and excellent lithographic quality, with illustrations characteristic of graphic design from the late 1920s. They constitute a source of great documentary 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 now scarce and especially valued by collectors of automobilia, historical advertising, Art Deco graphic design, and the history of the Spanish industry.
