Still, there are those that you can't help but hope for. Those variants that make you eye your children (our your future children) and wonder if a promise of handing over your first born will finally get you pieces like Stanley “Artgerm” Lau's cover for The Flash #8.
Flash vs Reverse Flash - sigh - more of a classic cover you'll be hard to find. And with children taking nine months of preparation, I don't think the above idea will come in handy for this one.
Hopefully Santa is a reader of IADW!
So what variants did you lust after but never snatch up?
