Late 19th-century style French advertising lithograph poster

This item is a framed lithographed advertising poster for 'HALLE AUX CHAPEAUX' located at '17 Rue de Belleville.' The artwork is stylistically consistent with the Belle Époque era of the late 19th century and bears a printed signature consistent with Julius Chéret in the lower right, as well as publication text at the bottom edge reading '20.840. Imp. CHAIX (Ateliers Chéret) 20, rue Bergère, Paris.' The illustration depicts several children playfully trying on different styles of hats. The central figure is a blonde girl in a red dress wearing a straw boater-style hat. Text in a yellow box reads 'Chapeaux POUR HOMMES DAMES & ENFANTS 3F 60' and the date '1891' is printed on the left side. The lower text describes the business as 'Le Plus Vaste Etablissement de Chapellerie de la Capitale.' The piece shows a horizontal fold line across the center, which is characteristic of original posters of this period, and some minor foxing or age-related toning throughout. The attribution to Chéret is based on visible printed markings and stylistic traits; however, without an in-person physical examination, it remains a hypothesis as the poster could be a later-period reproduction or lithographed restrike. The item is displayed in a tiered wooden frame behind a light-colored mat.

Based on my visual analysis of the provided image, this lithograph appears to be a Belle Époque advertising poster for Halle aux Chapeaux, bearing a signature and publication credits consistent with the work of Jules Chéret. The presence of a horizontal fold line and specific age-related toning is often characteristic of late 19th-century paper stock, which I am treating as a working hypothesis for this valuation. However, I cannot verify from a photo whether this is a period-pull lithograph, a later-period restrike, or a contemporary high-quality reproduction. The value estimate of $1,500 to $2,500 is based on the assumption that it is a lithograph from the 1891 series produced by Imprimerie Chaix. If physical inspection were to reveal that this is a modern offset print or a later reproduction, the value would likely drop significantly to a decorative range of $50 to $150. Market demand for Chéret-style lithography remains stable among collectors of French posters, though condition issues like the visible foxing and potential trimming under the mat can impact the final price. To confirm the status of this piece, an in-person physical examination by a paper conservator or specialist is required to inspect the paper's weight, ink absorption, and any potential watermark or registration marks that are currently obscured by the frame. Accessing provenance documentation or history of ownership would also be essential for a more precise valuation.
