Uncanny X-Men (1st series)
Title was originally just called X-Men until #142, when it changed to Uncanny X-Men.
Title was canceled with #66 but continued to be published until #93, reprinting earlier stories. Following Giant-Size X-Men #1 and the introduction of the "all-new, all-different" team, new stories began with #94.
Although the title was cancelled with #544, the series restarted with a new number #1 one month later.
