“Portrait of Jane Sutton with chickens in a yard between buildings”
Looks like it must be at the southwest corner of the Trustee's Office because that is the only large building with the back addition flush with the front (on its west side). This is the spot where visitors approach from the parking lot today.
The photo appeals to me for three reasons. First, it shows action - farm work in progress - rather than the typical "sit on the steps for your portrait" shot. Second, Jane is a Runyon descendant (granddaughter of Joseph and Jane/Ginny).
Third, it shows that Pleasant Hill was a working farm in the way that you might expect a Shaker farm to be... orderly but not perfect, not pristine, as a visit to the village today might suggest.
