The Ida Post Office Building was erected in 1923 by W.C. Reynolds, an early postmaster in Ida. It served as the Ida Post Office from 1923 until 1962. After that period, the building became a carpenter shop operated by J.E. Richardson. In 1997 it became the home of the Ida Museum, and in 2010 it was converted into the Fletcher Adams USAF 357th Fighter Group Museum.
