Exceptional historical documentary view capturing the marble sarcophagus of Unitarian minister and Union orator Thomas Starr King (1824 - 1864) in the churchyard of the First Unitarian Church on Geary Street. The tomb is formally festooned with evergreen mourning garlands and wreaths on the first anniversary of his death (and the day of Lincoln's second inauguration). 

Thomas Starr King was universally credited with keeping California firmly aligned with the Union during the opening stages of the Civil War, using his stirring oratorical powers to rally Northern sentiment and raise immense sums for the United States Sanitary Commission. His unexpected death in 1864 shook the nation, making contemporary photographic records of his memorial site key historical artifacts. Combined with scarce documentation of early San Francisco street rail transit in South Park and broad urban vistas, this grouping represents vital mid-1860s Pacific Coast documentation.
