From - Mythology : The DC comics art of Alex Ross.
I found these two details really interesting -
Zatanna
The model for this poster art was especially enticing for Ross to work with. "This is my wife, T.J., posing as one of Paul Dini's favorite characters. And T.J. is my favorite character."
Black Canary
"I've been telling Alex for years that we should do a book called Black Canary and Zatanna : Power of Fishnets," says writer Paul Dini, " and I will keep telling him."
