Faster Friends needs a little help.
I think some of the confusion comes from a change in the indicia.
Part One is “GREEN LANTERN/FLASH: FASTER FRIENDS” in the indicia. Part Two is “FLASH/GREEN LANTERN: FASTER FRIENDS”.
Those were from 1996.
Then in 2010 there was a DC Comics Presents special that combined both parts.
Right now Green Lantern / Flash contains both issues 1 and 2.
And then the Flash / Green Lantern is a duplicate of the DC Comics Presents special.
Whether you choose to combine parts 1 and 2 into the same series or split them based on the indicia, I think there’s still a duplicate.
I think there should be three issues when all is resolved, whatever they are called. Part 1, Part 2 and DC Comics Presents Special.
Thanks!
