This poster for the Godzilla Store in Tokyo is awesome!
We have the now-iconic Shin version of Godzilla, naturally, and behind him somewhat modernized but otherwise Heisei and Millennium influenced versions of Mothra, King Ghidorah, and Rodan - I'm assuming because we're a year and a half from them making a big splash in Godzilla 2.
But then there's what appears to be Biollante's tendrils at the bottom? That round growth thing that's a part of it certainly evokes Biollante's chest. Just for coolness sake or some reason behind it?
