Autograph Identification Help: Des Moines Prohibitionists photo

I know you're primarily looking for a signature ID, but since I'm not much help on that, here are the only two related photos that I have for comparison, both of the 1888 team (and both courtesy of tnfoto).

Posting a couple of better images of the letter and the signature. In reading back over it, and reviewing Barrow's biography (at http://sabr.org/bioproj/person/c9fdbace ), it appears that the writer was in Des Moines when Barrow's family lived there in the 1880's and either knew him well at that time, or came to know him well in later years. It is dated February 3, 1940 from St. Louis, MO. I still can't tell if the writer had any connection to baseball other than being a fan, but thought I'd give the thread one more bump with the better images before letting it die.
