It might just be the most famous absinthe poster from the Belle Epoque era, Absinthe Robette by Privat Livemont from Schaarbeek (Brussels, Belgium). This lithography (83 x 110 cm) was printed by J.L. Goffart from Brussels in 1896. This printer was mostly known for his educative posters which hung in almost every Belgian school at the time. I have tried to find out more about this absinthe, where it came from, and who made it.
In short, Absinthe Robette was the trademark of the Distillerie Petitjean & Cie, founded in Mons, Belgium. This factory also produced fine kirsch, amer and mirabelle. It was the second establishment of Petitjean from Saint-Loup (now called Saint-Loup-sur-Semouse) in the French department of Haute-Saône in the Franche-Comté region. This successful French distillery, led by Mr. Petitjean himself and in succession by his widow Mrs. Robette, hence the name of the Absinthe), counted 52 employees and an astounding 340 representatives in France, Belgium and possibly other countries as well.
Information is very limited, but when I find out some more, it will be posted right here.
