Sure there are a lot of minimalist and vintage style Star Wars posters out there - but this is the only place you’ll find quality advertising for the niche Intergalactic Travel Market. Planning a vacation? ”Cruise the galaxy aboard an Imperial Star Destroyer.”
There’s more below, but you can see all of these retro posters from the Tokyo subway telling people how to behave with explanations here, though I’m sort of fond of not knowing what they say in a weird absurdist take on Western and Japanese pop culture icons sort of way. Basically, they can be boiled down to “don’t smoke, don’t be an asshole, don’t spazz out, don’t leave gum on the floor” etc.
