BrianBrian,
I am not sure why this post didn't get some responses.  Yours does look like a printer scrap.  I have a blank backed Zieder 1909 that looks like a normal card, just blank backed.  I will get a scan posted soon.
I have only handled about 200 1909s, and have seen a roughly 50/50 split between framed and frameless.  I am sure Leon, Scott B, T Bob and others have more experience than this.
I have not noticed a connection between teams and back type -- that's an interesting finding.
Maybe Mark M. is reading and can offer his perspective...
