Swamp Thing Head Sketch

I've always wanted to get some sort of Swamp Thing drawing by Wrightson, and this one is pretty good. I'm not sure why the image was cut along the left side, you can see where the first part of his name got cut off and then the word comics underneath that. I'm not sure what was to the left of that. Then this piece of drawing paper was attached to a blue line art board. So you can see it's still a pretty big piece, but I'm not sure of the reason for the crop.
