[Paris]: Laboratoires Dujardin-Salleron, [circa 1890].
Broadside 37.5 x 28 cm. Contemporary to Louis Pasteur, Jules Salleron established a Parisian company specializing in oenological precision instrumentation, developing an acetimeter followed by his renown ebulliometer (still used today). Joined in the 1880s by Jules Dujardin, the company grew and continues to operate today. This pictorial broadside illustrates their oenological analysis laboratory and promotes their business to a Spanish-speaking clientele. On heavy cream stock printed in red and blue. Original metal mounting bars affixed to top and bottom edges. Small bend and slight creasing on lower edge with 3.5 cm tear along lower mount and 2 cm to the upper mount; some light wear and soiling, otherwise very good condition.
