I found this incredible artwork of Batman's Rogues Gallery years ago using a Google image search.
It reads, "Batman's ROGUE'S GALLERY" "Can you identify all 24 villains on the Darknight Detective's "most wanted" list? (See next page)"
However, I wasn't able to name all of the villains. I even got together with my friend Andrew Blackman and yet we were still missing three names. It really started to bother me.
I found it very difficult to find which comic this two page spread came from. An extensive Google search revealed nothing. But after identifying the artists (Dick Giordano and Denys Cowan) from their signatures on the bottom left I had some leads. I followed them up with my friend Cesar Perez and we both independently came to the same eBay posting. Because the person that listed the item included interior shots I was able to confirm that this was the comic:
Here is a cropped version of the scanned image with some visual adjustments applied (brightness, exposure, highlights, contrast, tint, saturation, and warmth). I used Adobe Illustrator with my friend Cameron London to crop out the spine and fix some of the irregularities, distortions, and printing artifacts. I also inserted the character names at the bottom.
