Wow. This is a blast from the past. Are you old enough to remember Johnny Sokko and his Flying Robot? It was a kaiju import from Japan, with bad dubbing and people in low budget costumes. No? There’s a video at the end of this post to bring you up to speed and/or infect your mind.
These posters are from Boiling Point and Geek Native have featured their retro work before. They’re actually a small indie publisher and you simply need to pop over to Etsy to check out their store.
You might well decide the posters are rather flattering. If you want to see more of BPCreative’s work then their Etsy gallery is a good place to look.
