The store/gallery is based in New York where you can purchase everything from a 1960s Swiss Scene Card of Casablanca for $150 to a 1933 Argentinian King Kong poster for $75,000.
As well as posters, Posteritati also sell books. The ones that caught my eye were Art of the Modern Movie Poster (2008) and The Independent Movie Poster Book (2005). If I was a rich man, I’d buy so many posters (and maybe a Fiddler on the Roof poster.)
