With the 1948 cover of Phantom Lady #17, artist Matt Baker helped give us comic book fans a code word we've used now for decades: “headlights”. It happened when Dr. Fredric Wertham, M.D., published his book, Seduction of the Innocent, which pointed out how murder, crime and sexual perversion were all part of the comic books kids loved. Wertham used the cover to point out that children called big breasts on comic book women “headlights”. (This page has been razored out of some of copies of SOTI I've seen. By headlights fans, no doubt.)
I've pointed out before that Wertham’s book is a good example of the Law of Unintended Consequences. It was used at the time to condemn comic books, but is used now to identify comics that belong on a special list of desirable collectibles. Interior art on this story is also by Matt Baker, and the whole issue was prepared by the Jerry Iger comic book shop, where Baker was a star. The publisher was Victor Fox, and the blobby printing was by some fast and dirty web press printing company of the 1940s, which didn't care that they were printing one of the most iconic covers and collectible comic books of all time.
