*Once a design firm comes up with the basic concept for a "campaign" to sell a film, artists set to work on rough sketches and sometimes more polished art. Here's an early sketch (front) for The Empire Strikes Back from the artist Sanjulian. Larry Noble came up with a different, powerful image (back) of Darth Vader practically punching through the paper, over an icy-cold scene on Hoth. It later was used for an Empire 10th anniversary poster. *Source: Back of card
