Vote for the Batbooks on the New 52 Thunderdome thread!
Here's the link to the whole story for those of you who only visit the Batforum.
Currently Birds of Prey is up against Frankenstein and Red Hood is facing off with Blue Beetle. Feel free to vote for or against them at your leisure. Each poll will go for 48 hours in the playoff stage.
Catwoman will be up against Voodoo in a couple days, and then in four days' time, Batwing faces off against All Star Western (sorry for those who like both books, that's the way the cards fell as far as rankings were concerned).
All the other Batbooks are in the main draw of the New 52 Thunderdome which should get underway around Thursday.
