I have a lot of doubt about there being any passes besides lack and the background color on any Topps Back until whenever they started doing color images on the back - 1992? *
I've seen scans of a yellow backed 1991 another member has, plus these few 72s.
But what I haven't seen is any card showing two background colors out of register, which would prove there were multiple color layers on the backs besides the background and he borders/text etc.
*The exception would be cards in the 68-71 range with the white backs which I think had a layer of white printed first before the two back colors.
