DC's The Source blog has posted a Batgirl teaser image that's got fans talking in their comments section. Who exactly is that behind the mask?

Barbara Gordon and Cassandra Cain seem to be the obvious and popular guesses, with Betty Kane, Misfit, Spoiler and Wendy -- Calculator’s daughter -- also making a showing. The other mystery seems to be who drew it; as many folks note in the comments, it is a nice piece.

Batgirl #1 is due in August.
