Showcase 1956 #34 - 5.0 - $225.00

Scientist Palmer is experimenting with his reducer lens to try and reduce objects in size without blowing them up, all without success. However, when he, Jean and students are trapped in a cave-in, he decides to use the lens on himself and save the others before he is destroyed. To his surprise, he is not destroyed as he becomes a human atom, and the lens later returns him to normal size.
