They have a lot of history. I’m also a pretty big fan of both characters, and enjoy neat wallpapers featuring them when I come across them. However recently I wanted a good high resolution wallpaper of the two; but was yielding little in the way of what I wanted with my google and bing-fu. So I found a series of wallpapers I enjoyed in the past and decided to combine them for this result that I’m now using for my background.
Characters of course are copy written property of DC Comics. I make no claim to the original work, merely the compositing of this fine artwork into something I enjoy on my system.
Have a good one.
