My original tumblr post was here. This image was first posted on tumblr by michaelmay and comes to us via hubungus. This illustration for a (I think imaginary) story Azure: Woman of Space was by Scott Wade. The link in the original post is now broken, but he appears to have a DeviantArt site here and a tumblr here.
The original is posted here by the artist, with an explanation: http://swadeart.deviantart.com/art/Azure-Woman-of-Space-Satellite-Soda-SDCC-2011-384521899
So the Woman of Azure wears green, not blue? Anyway, cool garters.
