Jim Sachs was brought to the "Ports of Call" project by Aegis (the publishing company) and worked together with Richard LaBarre on the images.
Jim Sachs was lead artist and LaBarre was learning from him. They both had been pilots in the military and had become neighbors after leaving the active service.
Jim re-used the title picture for Ports of Call in his abandoned [link=/game/20000LeaguesUnderTheSea.html]20.000 Leagues under the Sea[/link] project.
The german magazine Amiga Magazin did an article on Jim Sachs in their August 1989 issue. They previewed a screen from the project, while it was still in development, and you can clearly see the same sky, mountains and buildings.
