Superman 127 When There Was No Clark Kent Feb 1959 

This story probably inspired the episode "The late Mr.Kent" from Superman The Animated Series.

Superman is the secret identity. Not Clark Kent. He was brought up and raised a 'Kent' so that makes him a 'Kent' whatever anyone else says.

Rember this is when DC was.cutting.down violence to get the seal. Dell out sold DC with no code seal.Even when Superman was.on reruns. Mickey Mouse Was King.
