Cave of Cool for finding this for me.
It is not due out till late September of 2015. But I am thinking pre-ordering is a good idea.
I noticed there was a Batwoman one as well. But I can't justify getting two. I can barely justify getting one! At least there is a good reason for Zatanna to be wearing high-heeled boots; she is a stage performer and this is a costume. Batwoman should be wearing red combat boots.
