*Marvel: From the Good Doctor Collection this week, X-Men #64-66 were the last three issues of the original series to feature new material (issues #67-93 were all reprint), but each of these three issues has great significance. #64 featured the debut of short-lived X-Man but recurring character Sunfire; #65 (the last issue drawn by Neal Adams) featured the return of Professor X back from the dead and #66 guest-starred the Hulk, who Marvel always seemed to wheel out for the final issue of a series.
