Superboy 1949 #177 - 3.5 - $3.00

Superboy makes it seem that he has turned on his foster parents in order to protect them from Luthor's latest scheme against him.

Superboy accidentally unleashes a plague from an ancient Egyptian artifact, but is able to turn back the clock and prevent the epidemic.

Dev-Em arrives at Legion headquarters as a member of the Inter-Stellar Counter-Intelligence Corps on a mission to nab the elusive leader of the Cosmic Spy Legion, Morlock the Merciless, but loses the assignment to Superboy.

Superboy successfully completes Dev-Em's mission, with Proty II's help.
