Two great British things in one wallpaper! WOO!
Marvin the paranoid android from "Hitchhikers Guide" mashed into the Keep Calm and Cary On poster.
I made it 1920x1080 for easy HD wallpaper use. If you want to use this as your wallpaper, but have a different size screen, let me know as I would be happy to adapt it to your resolution
Also just so you know, that "crown" is the thinking cap (lemon juicer) from the Hitchhikers movie. It was NOT in the book however
Made in Illustrator with some post-processing in Photoshop.
