It turns out DC has started up again. The main Flash series from 1987 onward have been complete for a ehile, and DC had been working on filling in the 1959-1986 series when they stopped. Over the past two months they’ve added:
Flash/Green Lantern: Faster Friends, a two part miniseries starring Wally West and Kyle Rayner as they find one of Jay Garrick and Alan Scott’s old cases comes back to haunt them. (Also one issue showed up on LOST, mainly I think because they find a polar bear.)
Flash 50th Anniversary Special, in which three generations of Flashes battle the same villain across the ages, and a future Flash John Fox makes his debut.
DC First: Superman/Flash, featuring the first race between Superman and Jay Garrick.
Flash Secret Files #3, which introduced Hunter Zolomon.
Flash (1959) #107, which was skipped for some reason the when they started releasing the Silver Age Barry Allen issues.
And there’s also a digital collection of theMorrison /Millar /Ryan / Mhan run. The individual issues have been available already, but now you can get them all in one package.
