I've been reading about the 150 series and T206 Resource makes the claim that Wagner and Plank were late editions to the 150 Series and not part of the "original" 150 subjects.

They also say that the Sovereign 150 Series represents the original 150.

I've read the "Piedmont first" theory here and it makes sense for one reason - The Magie error is a Piedmont only back and Magie HAD to be part of the original 150, meaning the Piedmont backs were issued first.

But, that begs the question - Why were Wagner and Plank only issued in packs with Sweet Caporal? If Piedmont was first, it seems like those two would have been found in Piedmont packs. I realize that Piedmont backs exist for both but my understanding is that all of them were cut from unissued sheets. (1 Wagner and 4 Planks total?)

It does make it seem like both cards were released later in the 150 run.

And about late 150 subjects, any theories about Jennings being Piedmont 150 only?
