Friday’s Wayno/Piraro Bizarro (Wayno’s title: “Logo Design”):
(#1) (If you’re puzzled by the odd symbols in the cartoon — Dan Piraro says there are 2 in this strip — see this Page.)
There’s a relatively straightforward implicature from what Superman says, that there was a time when he didn’t wear an identifying logo — “the big red emblem” — but used only his spit curl (BrE kiss curl) to identify himself.
(Well, there is the rest of the costume, including the cape, but I suppose the idea is that those items would merely identify him as some superhero or another, speeding through the streets and airspace of Metropolis, but would fail to distinguish him from all the others. While the spit curl would have been something unique; it could have been, oh, a goatee, red eye shadow, pixy ears, a big butch metal neck chain, red knee pads with S on them, brass knuckles, high-heeled boots, any manner of things, but a spit curl ought to work.)
As it happens, in his early appearances, starting with Action Comics #1 in June 1938, Superman had the S shape on his chest, but not on his forehead. What to make of that? — Has he forgotten? Is he confabulating? Or does his use of “is too subtle” not implicate a spit-curl-only period?
Perhaps it merely conveys that when he started his career he, or maybe Martha Kent, realized that spit curls alone apparently are, as a general matter, insufficient to distinguish exceptional individuals from the herd, so added the logo from the beginning; in that case, he might have said “an S-shaped spit curl apparently would have been too subtle [for our purposes]”, so they axed the spit curl completely in favor of the much less subtle logo.
