After the marginal drips in Mural, ones like those used by Mitchell appear in Pollock's work for the first time in his 1952 Blue Poles.
The presence of the drips in the lower right corner serves as external evidence of the painting's vertical orientation, but someone with the kind of control Pollock insisted he possessed would want the orientation of the painting to come entirely from within.
It is unrealistic to suppose, in a work so driven by energy and passion as Mural, that Pollock should have noticed the drips in the lower right corner.
If I am right about the drips in Blue Poles, Pollock must have painted it on a vertical canvas, using runny paint, at least in part, the way Mitchell was to do.
