Real Photo Postcard of two women participants in the Centennial Pageant of Milo, Maine, on September 1-3, 1923.
They're identified on the reverse as Mrs. G. Warren Daggett, as the Spirit of Religion, and Mrs. A. P. Mills, as the Spirit of Education.
From brief online research, hopefully correct - corrections and additions requested:
Mrs. G. Warren Daggett was presumably Clara Louise (Brown) Daggett (1873-1942), second wife of George Warren Daggett (1862-1945), or Warren George Daggett.
Mrs. A. P. Mills was presumably Sara E. (Creighton) Mills (1870-1923), wife of Alonzo Putnam Mills (1870-1950) [other records show his birth year as 1872].
Milo, Maine, located near the exact center of Maine, was incorporated from Plantation 3, 7th Range, North of Waldo Patent, in 1823 and is known as the "Town of Three Rivers", the Piscataquis, the Sebec and the Pleasant.
