Blank back T212?
 

Wondering if anyone has seen - or has image of - a T212 Obak with blank back. This 1909 came out of a period scrapbook with a couple of hundred others - all having printed backs. It does not appear skinned. Any experience with similar Obaks?

John,

I had a couple many years ago, but I can't recall if they were 09's specifically.

T212 Blank
 

Appreciate the info. Have seen one other (1910) owned by a board member. Neither appear to be hand cut.

Here is a strip I used to own.,..More like a proof/incomplete printing strip though...
