Fairbanks fairy soap chromolithograph by Maud Humphrey

HELP!!! PLEASE!!! In the bottom photo is a framed picture of four seperate pictures. The one in the upper right is the one I am interested in... the victorian lady standing in a garden and holding a book. My grandmother had a framed print of that picture hanging in her house forever. When she died, my cousin took it. My sister DESPERATELY wanted that picture. My cousin did agree to let me examine it. On the back is printed that it was a promotional item given away by the Fairy Soap Company. Is there anyone who knows the name of the picture or artist? The closest I've come to identifying it is that it is similar in style to W.H. McEnte pictures. I would dearly love to find a copy of this picture for my sister. email me at [email protected]
