Joe, to print them after they were cut up would mean taking them from a sheet fed press to a letter press for the small run. Doesn't make sense and is really inefficient. And more than 1 color on a letter press is really, really tough. They could've had a small press but why? Easier to do everything on the same one.
I think it's more likely they laid out the front of the sheet as normal, and then laid out the back of the sheet as salesman sample ads, running those first to get them out. Since they were 3 card panels they hand cut them, and then changed the plate for the reverse of the sheet to the standard backs and printed them.
