Batman has alway been a favorite superhero of mine, while growing up I always had my foot firmly planted in the Marvel comics camp, The Avengers, Spider-man etc... But my secret shame among my fellow Marvel aficionados was the odd Batman comic, that and the camp sixties TV Show played constantly when I was a kid. Anyways Paperollies has a pretty awesome Batman papercraft for you in his amazing series of SuperPaperMen which you can grab here.
If Superman is more your cup of tea then you can grab him here. Check the homepage too for some other great paper model goodies
