The arcade game was published and manufactured by Hoei. Towards the bottom of the poster is the phrase "MODERN CONCEPTS IN THE AMUSEMENT INDUSTRY", then a logo depicting a set of wings, and then the words "HOEI international inc, HOEI manufacturing corp.".
There are a whole mess of Star Wars knockoffs here, so let's get started. First off are the AT-ATs, which were the first Star Wars related things I noticed when I found this poster at a flea market.
The second thing I saw was a probe droid, or "probot".
This next one is probably my favorite element from the art. There's a building that looks like a 2-1B surgical droid's head!
When I saw that, I knew I had to buy the poster! Also, to the right of 2-1B is a structure that kinda resembles IG-88, that cool, skinny droid seen with the bounty hunters in the Empire Strikes Back.
Behind the giant ape-man head is Cloud City, home to a good group of Ugnaughts.
There's a snowspeeder with a pair of AT-AT legs stomping it (like Luke and Dack's snowspeeder). Oh, and a bunch of ape-men are attacking it.
Within the snowspeeder debris is a chunk of something that looks like the upper half of a domeless R2-D2.
The last Star Wars sighting here is the eerie image of Darth Vader's helmet in the starry sky.
At the bottom right of the poster it states, "PRINTED IN JAPAN".
Click here to check out The Arcade Flyer Archive to see a flyer for Future Flash. It's very similar to my poster, but it features photos of the game cabinets.
Now for story time! The gentleman I got this from said the poster was hanging up in his dad's gaming store roughly fifteen to twenty years ago. He noted that he thought the ape-man looked kinda like "Chew-wobba".
