Black Jack, Bally, 1977. A detailed and elaborate Jack (like on playing cards) decorates this machine. I own one, so clearly I like it.
Big House
Big House, 1989, a goddamned Gottleib.
This one is jailbreak themed. And that would be fine. But most of the characters drawn in the backglass art are anthropomorphic caricatures of 1950s Hollywood stars from the mob movies of the era. Two have the heads of dogs, one appears to be a cat, one is a rat, all dressed in black and white striped prison uniforms… and there are also a few humans on the glass, all of which look like they’re the “good guys”. It’s very noir-adjacent.
Barracora
Barracora, Williams, 1981.
This is the head of an alien woman. She is yellow. She has tentacle or horn like protuberances of significant size growing out of her face. There appears to be the head of a barracuda growing out of each side of her temple.
Behind her are green things that might be trees, eggs, alien grenades, who knows.
Avengers Infinity Quest
The Avengers Infinity Quest (Premium), Stern, 2020.
Typical modern Stern, in that the art is clearly Marvel and a little boring. Thanos sits in the center with his right hand on a pile of skulls and his left hand In the glove which is on fire. To his left and right are ¾ profile head shots of other characters in the movie/game.
