I don't know if you know this, but Batman isn't exactly a happy guy.
New city, same shade of gray... but not for a lack of trying.
Here's an image of Batman looking at a dog. There you go.
2016 takes something else from us, and this time it's Chew.
The gift of Clayface, TAKE IT IN MAAAAAAAAAAN. (reference!)
Interesting--when I read that, I assumed from the description that it was meant to be the Talon that we've been seeing in Batman this whole time. Now that you mention it, considering the time-frame and what Winnick has said, having this be the TDK Talon makes more sense.
He could show up in Batman too, who knows. I read the actual post after the fact, I just saw "1950s," that picture, and remembered it was the same one on the cover of The Dark Knight #9.
