It appears to be based on an artwork created by Frank McCarthy without Connery / diver fighting. That artwork was rarely used. The only instance I can think of is the artwork used in the Milton Bradley game from 1965.
Closer investigation of the poster version reveals that it's based on this artwork but was cut-up, re-painted and Connery / diver were added on top, see details below.I don't even want to think about if the original artwork was cut up...
