## About Henri Cassiers

Henri Cassiers (1858–1944) was a Belgian painter, illustrator, watercolorist, and poster artist closely associated with the Art Nouveau movement. Born in Antwerp as Henricus Paulus Emilius Victor Cassiers, he also used the names Henry and Hendrick Cassiers and typically signed his work 'H. Cassiers.' Active from the late nineteenth century through the early twentieth, Cassiers built a reputation for vibrant travel and tourism posters, watercolors of maritime and coastal subjects, and book illustrations that blended decorative elegance with a distinctive graphic clarity. His poster work placed him among the notable European affichistes of the period, and his designs reflect the flowing organic forms and bold color palettes characteristic of Belgian Art Nouveau. MoMA holds examples of his work, and the RKD Netherlands Institute for Art History records over 160 images attributed to him. Collectors most often encounter Cassiers through his original posters, watercolors, and etchings at auction.

## Common works and media

Henri Cassiers is most commonly encountered in appraisal and auction contexts as the creator of Art Nouveau travel and tourism posters, often produced as color lithographs. He also produced original watercolors depicting maritime and coastal scenes, etchings, book illustrations, and graphic design works. His printed posters, typically promoting seaside destinations and transportation routes, exist in multiple formats ranging from original stone-lithograph editions to later reproductions. Original watercolors and drawings by Cassiers appear less frequently at auction than his poster work. Collectors should distinguish between original prints, later restrikes, and reproductive reproductions when assessing value.

## Market and appraisal context

Henri Cassiers' work appears across several auction categories, including vintage travel posters, original watercolors, etchings, and book illustrations. His travel and tourism posters from the Art Nouveau period are particularly sought after by collectors of graphic design and poster art. When evaluating a Cassiers work, appraisers consider the medium (original watercolor versus printed poster), condition, date of execution, subject matter, and provenance. Works from the 1890s through the 1910s, the peak of his poster production, tend to attract stronger collector interest. Authentication should account for his known signature ('H. Cassiers') and monogram ('HC'). Auction results should be consulted for comparable pricing, as market values vary significantly between his original works on paper and his printed poster editions.
