The Flash #193

Captain Cold takes center stage on this December 1969 cover, leering menacingly as he brandishes his cold gun — and what he's done to the scarlet-suited Flash is literally stamped CENSORED, with only the hero's limp, outstretched hand and crumpled costume visible beneath the block letters. Murphy Anderson's cover art leans into pure provocation, with Cold's taunting speech bubble — "Do you dare read this issue and find out for yourself!?" — turning the Comics Code's very existence into a brilliant piece of showmanship. With a story titled "Captain Cold Blows His Cool!" and one of the Silver Age's most playfully audacious covers, this one is hard to resist.
