Atari space riders
Not sure what the helicopter had to do with highways, but here is another one with a non-related aircraft, on the BG...
Pirate Gold, Chicago Coin, 1969.
I like how you tied in both the theme and the artist (Christian Marche) to Jolly Roger.
Last clue artwork has a European or foriegn mfr flair to it,
And also looks like a buccaneer or swashbuckler femfatale look.
Still have no idea though.
