Superboy #39

From March 1955, this DC ten-center delivers a wonderfully tense cover by Curt Swan and Stan Kaye: a boy in green leaps fearlessly up the side of a crumbling building, confidently shouting to Superboy that he can handle the falling masonry on his own — while the Boy of Steel and a crowd of onlookers watch in wide-eyed disbelief from below. The issue features "The Boy with Superboy Powers!" alongside the interior story "The Boy Tycoon of Smallville," with art by John Sikela, making this a packed and irresistible slice of Silver Age adventure.
