鉄人28号付録 [Tetsujin 28-go Furoku / Tetsujin 28-go Supplement]

横山光輝's Tetsujin 28-go Furoku, published by Kobunsha from 1956 to 1966, served as a supplementary comic series tied to the original Tetsujin 28-go manga. Spanning 65 issues, this companion series expanded the world of the iconic remote-controlled giant robot through additional stories and illustrations, all penned and drawn by the legendary creator himself. While less known than the main series, it offers a deeper look into the early era of mecha manga and showcases Yokoyama's prolific output during the medium's formative years.
