The Flash #126

This 1962 DC gem features a cover by Carmine Infantino and Murphy Anderson that puts the Scarlet Speedster in genuine peril — Mirror Master has somehow transformed the Flash into a reflective statue and now levels a gleaming ray-gun at him, threatening to shatter him into a thousand pieces. The bold cover copy promises "A New Mirror Master Story… The Doom of the Mirror Flash!" and the villain's triumphant pose makes it easy to believe he just might pull it off. John Broome and Carmine Infantino were firing on all cylinders during this Silver Age run, and this issue captures exactly the kind of wild, inventive threat that made the era so irresistible.
