Thanks to Jorge, I was able to add the Brown cut to my “Signature Collection.”
Once removing it from the prior custom, I was able to expose the front and back ends of the signature, including the traditional upward flourish of the “n”. And, upon doing some research, I learned that the signature below Brown’s was of Ed F. Leever, who was an insurance agent in Terre Haute, Indiana, which happens to be where Brown was from — excellent provenance, to be sure.
