Adventure Comics #357

Adventure Comics #357 (On Sale: April 27, 1967) has a more standard Curt Swan/George Klein cover.

Inside "The Ghost of Ferro Lad" is by Jim Shooter, Curt Swan and George Klein. In it the four Legionnaires who fought alongside Ferro Lad against the Sun-Eater, Superboy, Cosmic Boy, Sun Boy, and Princess Projectra, place a wreath at his memorial on Shanghalla, the cemetery satellite, then return to Earth, each obsessed with his memory. Meanwhile, a strange object from space pierces the walls of the Legion Clubhouse, and implants itself in the master control panel.

That night, the four heroes battle an unseen foe who causes nearly every object in the Clubhouse to attack them. After the barrage ends, a message burned in the wall indicates that Ferro Lad's ghost is haunting them, and Brainiac 5 and Saturn Girl, enroute to a law-enforcement convention on another planet, are summoned back to the Clubhouse to hear this news.

The ghost reappears to the foursome later that night and attacks, while Brainiac 5 attempts in vain to detect it with his equipment. When Saturn Girl tries to sense it with her powers, it shocks her into unconsciousness. The ghost departs after destroying Ferro Lad's belongings, and Brainiac 5 is as perplexed as the others.

After putting Saturn Girl in the care of doctors, the other Legionnaires hold a séance, with Princess Projectra as the medium, in an attempt to contact Ferro Lad's ghost. The ghost appears, and orders the Legion to disband, which they do. Reprinted in Best of DC #24 and Legion of Super-Heroes Archives Vol. 6 HC.
