Superboy #156

Marking Superboy's 20th anniversary in style, this Giant 25-cent spectacular from 1969 features two book-length novels headlined by "Superboy's Farewell to Smallville." The cover, penciled by Curt Swan, presents a larger-than-life Superboy gazing down at an open comic page that teases dramatic scenes — a caged Clark Kent, Superboy in flight alongside Krypto, and an emotional crowd gathering as the Boy of Steel apparently prepares to leave his hometown behind. It's a wonderfully nostalgic package, with Otto Binder's writing and Curt Swan's interior art promising the kind of heartfelt adventure that made Superboy a beloved DC staple throughout the 1960s.
