Sawara - Master and Slave
A notable contribution to the letter 'S' by Sawara. The leather jacket suggests some photo trickery here but it helps define the status of the 'M' rather nicely. I'm not sure about that bulge though!
I don't have any other information on the artist or a link I'm afraid, but a reader has kindly corrected the name for me and given a little information in the comments below.
