Supergirl #20 (June 2018) is now out and if you can possibly direct your eyes away from Supergirl on the cover, you will notice in the lower right-hand corner of the variant B cover there is a stamp-thing saying “80 years”. Superman first appeared in Action Comics # 1. The issue with a June 1938 cover date was released in May of that year. Action Comics will be celebrating its 1000 issue in just a week from now. This sadly enough marks the end of the current run of this the seventh Supergirl series.
Supergirl’s pose on the cover is reminiscent of her Post-Crisis return appearance in the final page of issue #13 of Superman/Batman (October 2004).
