Movie posters, particularly from long ago, were designed to be striking but disposable - pasted up for a short period of time to promote a particular film, only to be pasted over with a new one soon after. So those that have survived are rare by definition. As well as the movie itself, they represent the moment in time, becoming both pieces of art, and historical artifacts. Sotheby’s Original Film Posters Online auction has a number of these rare and unique posters, including many for movies that went on to be household names - and Academy Award winners. Click above to take a closer look at the artwork for these historic films, and discover what they won their Oscars for.
