This is the last issue of the original X-Men series which uses the original logo title "X-Men" (originally "The X-Men," with a definite article). Beginning with the following issue #114, the series logo title on the cover will change to "The Uncanny X-Men."
This title change will not actually be reflected in the indicia issue #142, but we list all issues of the series as "The Uncanny X-Men" (or eventually "Uncanny X-Men", dropping the article) beginning with #114.
