Images of it are rare on the internet, so I've tried to scrounge up whatever Astro Boy images that I could find from it. F-Man posted a few of these images on his Tumblr.
If anyone can find larger and/or clearer versions of these images, feel free to post them in this thread.
A forewarning to everyone that some of the content in this thread is a tad bit risque.
Here's an excerpt from one website that reported on the event back in 2010:
Patrick W. Galbraith wrote:September 18, 2010: the Tokyo Anime Center in Akihabara is hosting a preevent for a new exhibition on Tezuka Osamu. I walk in expecting to see a tribute to the father of modern manga and anime, a man deified as a "god," but find instead Osamu Moet Moso (Osamu moetto mosso). The exhibition claims as its mission "to extract and embody Akiba-like elements contained in Tezuka Osamu's works." This seems to mean extracting "moe elements," or those elements that trigger an affective response in fans, from Tezuka's characters and aligning them with popular manga, anime, and games in Akihabara, a hotspot of otaku consumption and culture. click for spoilerAmong those contributing illustrations to the exhibition are Itō Noizi, Kei and Yoshizaki Mine, known for their bishōjo (cute girl) characters. In line with contemporary and local tastes-and despite the involvement of Tezuka Productions, a company entrusted with preserving the creator's legacy-many of the characters on display look more erotic than wholesome. I stop in front of a rendition of Astro Boy, noting that his red boots have been elongated to look almost like "knee socks."
