Antiques expert Judith Miller writes in the U.K.'s Daily Telegraph of “Poster Art’s third great wave of popularity.” The first wave came with the birth of the art form in Paris in the late 19th century; the second in the psychedelic 1960s, when black-light posters on dorm room walls were as ubiquitous as bell-bottoms. Today, collectors will pay six figures for rare images.
Read the Telegraph story for more on how poster art has evolved as both a lithographic art and commercially viable advertising venue. There is also a handy checklist of what to look for when buying. And, if that piques your interest, check out Swann's upcoming Vintage Posters auction, in which all genres—from art nouveau to modernism—are represented, with an emphasis on skiing and other winter sports posters.
