Superman #3/1969

In "Die unsichtbaren Rätsel des Mr. Sphinx!", Superman faces a chilling test of loyalty when a young man he once helped, now grown into a figure of menace, is sent to kill him on orders from a supposed father figure. Written by Jerry Siegel and brought to life with Curt Swan’s iconic art and John Forte’s inks, this 1969 tale explores identity and redemption in a story where the true challenge lies not in strength, but in recognizing the truth behind the mask. The cover, by Irv Novick, captures the tension of a moment poised between destiny and doubt.
