Vintage thermometer with an advertisement for the “Martini & Rossi” brand, Europe, 1890–1910

Rarity and Value
This original Martini & Rossi advertising thermometer is a rare survivor of late 19th–early 20th century commercial design. Produced as a functional promotional object, such thermometers were manufactured in limited quantities and intended for everyday use, making intact examples scarce today. Branded advertising pieces from this period are highly valued for their historical authenticity, graphic quality, and strong association with one of Europe’s most influential beverage houses.

Discovery and Significance
Created between 1890 and 1910 by the factory “Jaco et Bonacker,” this thermometer reflects the rise of branded visual culture in Europe during the early age of mass advertising. Objects of this type were displayed in shops, cafés, and distributors’ premises, serving both practical and promotional purposes. It represents a formative moment in marketing history, when industrial production and graphic identity began to shape consumer perception.

Morphology and Preservation
The thermometer consists of a printed tin plate mounted on a wooden support, with a central glass tube set into a metal housing. The vivid green background, typography, and bottle-shaped illustration remain clearly legible, showing careful preservation. Surface wear and patina are consistent with age and use, enhancing the object’s authenticity without compromising its structural integrity or readability.

Human and Scientific Connection
This thermometer stands at the intersection of science, industry, and culture. It demonstrates early methods of temperature measurement while embodying the evolution of advertising and graphic design. As a museum-style exhibit, it offers insight into material technology, branding strategies, and everyday objects that shaped social and commercial environments at the turn of the 20th century.
