Reprint comic packaged with the Marvel Legends Storm action figure in 2004.
Marvel consistently credits this cover to Marie Severin and Sal Buscema. The original art was signed Sal Buscema. Buscema fully rendered a Severin sketch for the cover of #69, so it seems likely that was the process here.
Before the discovery of the original art, we had previously considered several possibilities: Sal Buscema pencils and Al Milgrom inks with the Storm figure penciled and inked by Dave Cockrum per Steve Whitaker; Dave Cockrum pencils with Sal Buscema inks (with alterations on Cyclops, Colossus, and Professor X by Romita) per Nick Caputo; Marvel's Official Index to the X-Men #2 gives the penciller as Marie Severin and the inker as Sal Buscema; Sal Buscema pencils and unknown inks per the original indexer.
