AFR Superheroes was a range of stickers I designed in 2005. I stuck them all over any city I visited during that time. I drew superhero ideas from comics, from video games and sometimes from parodies of heroes (Steroid Girl started life as a parody character of this series that I redesigned).
I've recently created AFR Superhero tshirts on Redbubble, you can grab them here - http://www.redbubble.com/people/afrenasia/collections/317116-afr-superheroes
Stickers sold out unfortunately. Hassle me and I might make more ;)
