What exactly do we think of as "classic movies?" What are the common elements by which we know them? The first thing we acknowledge about classic movies is their age -- these movies are relics of the past, left over from a world greatly different from our own that's now behind us. We probably think of them as black and white, a reflection of the state of technology's advancement at the time of their creation. Maybe star performers of classic hollywood come to mind -- Clark Gable, Henry Fonda, Orson Welles, Marilyn Monroe, Mae West, Joan Crawford -- actors who shared a special, unique charisma that was as much a product of their time as the technology that brought them to their audience. Let's look at the last thing I can think of that is inseparably tied up with classic movies in this way: the posters that accompany them.
The above posters reflect the older creative sentimentality present in the time they came from. They also reflect the technological means available for their creation in their time, just like the monochromatic color scheme of the films they were used to promote. Both the posters and their films capture the period in history they came from, and what I like about them both so much is that they have the ability to take our minds back to their time by the simple act of looking.
