JimBFrom scans posted here we know:
1. T206s were printed vertically - often, but NOT always with the same card on top and bottom.
2. T206s were printed horizontally with different cards being printed next to one another.
I think it is safe to infer from this evidence that T206s were produced on sheets that extended both horizontally and vertically with multiple different cards per sheet. Why no sheet has made its way in uncut form to 2007 is a mystery, but that alone is not evidence that they were not produced on sheets.
