Here is my concept of a 96-card printed sheet comprising of the T206's in the 460-only series, which I refer to as the "Exclusive 12" subjects.
These 12 subjects were printed on a sheet of their own. Separate from the other 36 subjects that were printed with only 460 series backs.
This scan represents a very plausible illustration of my "columns of 12" hypothesis.
