Adventure Comics #428 (August 1973) is a notable Bronze Age DC key featuring the origin and first appearance of Black Orchid (Susan Linden-Thorne).

This CGC 9.0 copy with White pages presents as a high-grade example of this increasingly recognized first appearance. Black Orchid later gained renewed attention through Neil Gaiman’s reinterpretation and broader DC Universe integration, strengthening long-term collector interest in her debut issue.

The striking moonlit rooftop cover, illustrated by Bob Oksner, delivers classic Bronze Age atmosphere and strong display appeal. Origin issues and first appearances of female DC characters continue to show increasing market demand, particularly in certified high grades.

Encapsulated and authenticated by CGC, this copy represents a strong Bronze Age DC investment piece and a key addition for collectors building out first appearance portfolios.

A standout issue within the early 1970s Adventure Comics run.
