Children of the Atom #2 Variation B non-existant

[Brian Price]

Children of the Atom #2 Variation B - Days Of Future Past Variant Cover by Javier Rodriguez does not appear to exist.  Javier Rodriguez did a series of 6 Days of Future Past variants on certain X-Books with September and October 2020 cover dates.  The cover date on Children of the Atom 2 is 6/1/2021, and I couldn't find any such Days of Future Past cover, just 3 other covers which are all accounted for in ComicBase.
