A vintage lithographic poster created for the 1980 Montreux–Detroit International Jazz Festival, celebrating the cultural partnership between the renowned Montreux Jazz Festival in Switzerland and Detroit’s influential jazz scene. The minimalist composition features a stylized female figure intersected by a rainbow-colored diagonal form, accompanied by the Swiss and American flags and festival dates. Executed in a bold graphic style characteristic of late 20th-century poster design, the work reflects the international spirit of the festival and Detroit’s longstanding legacy in jazz and contemporary music culture. The poster remains a collectible piece of music and graphic design history. Dimensions: 32.5"h x 23.25"w x 1"d (framed). In good vintage condition.
