Have you ever seen another example of this curious "BIOGRAPHY" pull tab? Mrs. J. E. Eberts filled it out in 1897, ten years after the patent date, so maybe there are more out there. It will take, however, a look at the patent information to see if photographer Brown was the actual patent holder.
I question the value of the tab (which was meant to be pushed back under the brown paper holder on the back) for a cabinet card. But it might have proved very handy on a tintype, which have hard-to-write-on black or brown metal backs.
