Andrew,
You mention Rowan and Scanlan as being found with Piedmont Factory 42 backs. Are there any other of the aforementioned SP's that are typically found with this back?
In your experience do SP's with the Piedmont Fact. 42 back carry any premium? Especially compared to the more common cards with said back?
I have this Hippo Vaughn (which I found to be one of the more difficult SP's) that I noticed has a Fact. 42 back.
Apologies for the scan, but I can assure you that the back is Fact. 42.
I also have a Kirb White with a Piedmont Fact. 42
