Justice League #59 is in stores March #16, 2021, just in time for the Snyder Cut of the Justice League movie on HBO Max on March 18. The kicker is the book is supposed to feature a new villain named Brutus, who comes from the same planet as Naomi. DC just dropped three ratio variants for the book, just before FOC.
The three variants are black and white versions of the regular covers, look to be full pencil versions.
There is a Justice League #59 1:25 with pencil art by Liam Sharp
A Justice League #59 1:50 with pencil art by Lee Bermejo
And a Justice League #59 1:100 with pencil art by Jim Lee
These are all available on TFAW with an Final Order Cut Off date of tonight. These, along with all the other cover of Justice League #59 are available for pre-order now with the FOC date of 2/21/21 (tonight).
