Comic art legend Jim Steranko created some amazing conceptual illustrations prior to even casting Raiders of the Lost Ark. I can easily imagine these as covers on some 30's or 40's pulp magazine with the Indy logo and a 10 cent price. They perfectly capture the movie serial spirit that inspired Lucas and Spielberg to make Raiders.

The latter illustration was used as the box art for the Raider's board game by Kenner. Note that the cigarette disappeared.
