Found these awesome guys on eBay awhile back and had to save a picture to share here. Figures of Ham Egg, Ban Shunsaku, Lamp, and Dr. Ochanomizu, each sharply dressed in their suits. Pretty rare to find much of any sort of merchandise based on the Astro Boy/Tezuka supporting cast, let alone in a group like this. I don't have any other information about where they are from or what they are made of. One has to wonder if there are any more figures in this range!
