Share 'Research: Hill and Adamson Carbon print, 'Redding the Line''

Hello, I am looking for information about this carbon print of Hill and Adams's Redding the Line. I understand that these carbon prints were made around 1916 by Jessie Brown Bertram. Would any member know where I can find more information about Bertram? Where these made to be sold commercially? Did she print other photographer's images? Thanks in advance, David McGreevy
