Just to note, the tag should be "giganta". Gigantor is the translated version of Tetsujin-28, probably the precursor of pretty much all modern mecha anime.
Not being snide or anything; I just found that amusing when I saw it.
My bad -_-; I always had difficulty in remembering how to google this one : d Guess I got kinda lazy when tagging the uber set of 'Giganta' pics that got uploaded recently. ^_^;
