Journey into Mystery volume 1 was a comic that began publication in 1952 by Atlas, and although it wasn't until the eighty-third issue that Thor even appeared in comics, let alone the title, it is most often linked to his character. This is why after releasing the one hundred and twenty-fifth issue of the series in 1966 that the series changed its name to become the first volume entitled Thor. As of #407, the book was renamed The Mighty Thor (vol. 1) until #491 when it returned to simply Thor. In 1996, after 502 issues of the series the name changed back to Journey into Mystery (vol. 3) which is what it was called up until its end in 1998 with issue 521. Although these later Journey into Mystery issues (#503-521) spin out of Thor vol.1, they are not counted in the collective Thor series.
