Well... not really.
In the comic I'm currently working on (my creator-owned thang), I wanted to have some movie posters up in certain places. I joked on Twitter that I'd slip one of my favorite characters, Atomic Robo in there, and Robo artist and co-creator Scott Wegener said "go for it."
So I did, cos it's just too cool to pass up.
I didn't want to spend hours on an image that'd be tiny and covered with foreground images in most of its appearances, so it's a very simple layout, and not a very dynamic pose. I also didn't use the actual Atomic Robo logo, as I'm not sure of the exact legality of that. The "text" below is unreadable, as I just pulled it from a real movie poster (I'm not even sure what the movie was - I just took the first easy to isolate poster I could find in Google).
And there you have it. A very blatant nods to one of my favorite books out there (why aren't YOU reading it?).
