I've become less convinced that the size was 25x19 for all the runs, different runs within a series, different brands etc. The layout Pat has for the more complete scratch is at least 17 wide, and probably wider.
I do think that some runs, especially for the smaller brands could have been done on a 19x25.
ALC would have used whatever was the most efficient based on the size of a particular order. The place I was at had a press that couldn't do anything larger than 81/2 x11. And a few times did smaller jobs.
There was also a 24", and 2 35s, and eventually a two color 35.
All the big presses could run smaller sheets, but we tried not to since it wasted a lot of paper.
By the numbers, there are some groups that divide nicely with 12, And others that fit 17 better.
The big group Pat has found I believe repeats after 17, leading me to think that one layout was perhaps as wide as 34.
If any group was going to be done on a large sheet it would have been Piedmont.
19x 25 is/was a standard paper size, but there were others.
