I have done some shading with coloured pens, 44 cells in one colour and 33 in the other, and the second cells 'fit inside' the first. However, I have no idea what I am looking at, unless it is the garment which one of the unclued entries traditionally wears in an eccentric manner. Is this it?
I am way out of my comfort zone with this theme. I thought at first that there must be someone called THE KNOB but fortunately this was unnecessary.
