The caption in the final panel of the original version says: "You'll find the cataclysmic conclusion of this two-part thriller in Avengers #53! On sale now!" The caption is altered here to read: "You'll find the cataclysmic conclusion of this two-part thriller in Giant-Size X-Men #1". Giant-Size X-Men #1, on sale the month following X-Men #93 (May 1975 cover date)was originally supposed to include a reprint of Avengers #53. Instead Giant-Size X-Men #1 featured a new story which filled the entire book and introduced the new team.
This was the last issue to include reprints. New material began with #94. Avengers #53 was finally reprinted three years later, in 1978, when both X-Men #45 and Avengers #53 were reprinted in Marvel Triple Action #s 45 and 46. Updated information per James Serpas (July 6, 2005) and Tom Hartley (June 8, 2011).
