The tiny Chamberlain, Maine Post Office, 1913, which I later knew well as a kid. We vacationed at a seaside cottage in that tiny town every summer.
The passenger in the car is "Minnie" Tukey, named first postmistress when the PO opened in 1905, retiring in 1953 after 48 years of service. The driver of the Model T is Cora Tukey Shaw. This tiny PO building was sometime later moved a short distance down to the "main road" (dirt at the time)..After Minnie retired, her nephew Arthur, who has assisted for years, served as postmaster from 1953-1973.
