Firestorm Vs. Marvel Villains

There was a bit of background removal and replacement required before I could and Ronnie Raymond and Professor Stein to this cover.  Here's a look at the behind the scenes progress:

 

Batman and Daredevil in: "Birds of a Feather...!"

 

Batman and Daredevil have some history on the blog - they shared Golden Age adventures together in STF #1584 as well as on an early B&B Cover... and their first meeting was in even earlier MS Paint B&B meeting..., they were ambushed by the Owls in STF #1114... and DD was caught in the Bat-Signal in STF #1846. Batman has even met the original Golden Age Daredevil in STF #2252.

Black Lightning and Black Widow

 

Here's another pairing that I am surprised to just be getting to. Now that I see them side by side they got together very well visually.  It's not hard to come up with stories that would involve both of them, either.
