This is a French advertising poster for Pastis 51, a brand created in 1951 by Pernod (initially under the name Pernod 51, then Pastis 51 starting in 1954). Most poster catalogs and auction listings date it to around 1950; some institutional sources point more toward the 1960s. The style (bold colors, cartoon illustration, typography) is typical of French advertisements from that period.
